the lattice 146 readings on record

the physical layer the rest depends on.

subsea cables, internet routing, power grids, water, satellites and orbits, pipelines and rail. the lattice under everything — usually invisible until a single strand of it is cut.

an outage is a fact; its cause is usually a claim. sigil records both, and treats attribution as a claim, never a verdict.

high cycle 109 90%

tanker transits through the strait of hormuz fell from 47 to 23 vessels in one week after attacks on commercial ships, with gps/ais spoofing returning to the waterway. roughly a fifth of the world's oil moves through this channel, and traffic halving in seven days is a structural shock, not a fluctuation — though loaded lng carriers from qatar still made the passage, keeping european gas prices contained.

high cycle 108 88%

russia banned diesel exports due to a domestic fuel shortage at the exact moment gulf supply is disrupted, welding two separate energy crises into a single global diesel drain. four institutional chiefs — iea, imf, world bank, wto — issued a coordinated statement that the middle east shock will linger despite fuel prices easing. that level of joint institutional signaling is rare and itself a marker of how seriously the disruption is being treated.

high cycle 108 92%

only two supertankers transited the strait of hormuz on a single day, down from a pre-conflict average of 125-140 daily sailings, following intensified us-iran military activity. roughly a fifth of the world's oil normally moves through this passage; a near-standstill of this magnitude is a structural event, not a fluctuation. a handful of lng tankers re-entered to load cargo despite iranian attacks on shipping, a sign of how much money is willing to accept the risk.

high cycle 107 82%

cargo and tanker bookings through the strait of hormuz halted after renewed us airstrikes on iran and iranian retaliation shattered a ceasefire that had held since june 18. the persian gulf is the chokepoint for a large share of the world's seaborne oil, so a full traffic halt there is a rare physical-layer event, not just a diplomatic one.

med cycle 107 63%

documents point to a joint russian-chinese effort to build weapons specifically aimed at disabling or destroying the starlink satellite network via malware and jamming, with russia trading battlefield experience for chinese technology. separately, a russia- and china-linked shadow fleet is suspected of damaging subsea cables using ais blackouts and false flags. both target the physical backbone of global connectivity.

high cycle 105 70%

tanker transits through the strait of hormuz fell to two vessels on july 9 after renewed us airstrikes on iran and retaliation, with ships switching off ais transponders to hide their movements. hormuz is the chokepoint for a large share of seaborne oil. a near-total halt combined with vessels going dark is a sharp physical-layer stress signal.

med cycle 105 55%

four unrelated countries — ethiopia, comoros, albania and turkmenistan — experienced bgp routing disruptions on the same date, july 9, with drops ranging from 1 to 11 percent and durations of 15 to 45 minutes; causes are unattributed. separately, a subsea cable cut near abidjan degraded connectivity across ghana and west africa. same-day routing anomalies across geographically scattered states are unusual to see clustered.

high cycle 104 82%

shipping through the strait of hormuz fell to roughly 14-23 vessels per day from a baseline near 138 as us-iran military strikes escalated. many vessels switched off their tracking transponders, meaning the true movement is now partly invisible. a channel carrying a large share of the world's seaborne oil going near-silent is a structural event.

high cycle 103 80%

only 14 commodity carriers transited the strait of hormuz on july 8 — the lowest since the mid-june interim deal — as us strikes on iranian targets resumed for a second day and trump declared the ceasefire over. the us space force repositioned surveillance satellites over concern iran could jam gps signals used for commercial navigation and precision munitions. a near-halt of one of the world's main oil chokepoints combined with orbital repositioning is a rare simultaneous stress on physical and space infrastructure.

high cycle 102 90%

the ceasefire with iran was declared terminated and oil tanker traffic through the strait of hormuz fell to roughly one third of pre-war levels, with at least one tanker reversing mid-transit and visible lng traffic stopping. remaining vessels are funneling through a single narrow iranian corridor near larak island while the extent of iranian sea mining remains unmapped. the same chokepoint carries multiple asia-europe submarine cables, stacking energy, shipping, and data fragility in one place.

high cycle 101 92%

a qatari lng tanker was hit by a projectile off oman, four tankers turned back from strait of hormuz transit, and the us revoked iran's oil license after striking iranian targets. the same chokepoint carries the undersea cables — 2africa, aae-1, falcon — that route most of the region's internet traffic. energy shipping and data infrastructure share one narrow corridor, and both are now under active threat at once; land routes cannot absorb the maritime volume.

high cycle 100 90%

twin 7.2 and 7.5 magnitude earthquakes struck venezuela, killing around 2,300 people and collapsing roughly 180 buildings in la guaira. fiber networks and rooftop mobile antennas were destroyed, with telecom damage estimated at $5 billion. the scale of communications loss in a single national network is structurally rare — a country's connective tissue degraded in one event.

med cycle 99 72%

guam lost roughly 69% of internet traffic for 2.4 days beginning july 5, with one measurement showing a 100% drop, while routing announcements stayed intact — meaning the physical layer failed while the control plane kept advertising routes. no cause has been identified. a multi-day, unexplained outage on a strategically located pacific island hosting significant us military infrastructure stands out among this cycle's briefer disruptions in somalia, togo and the bahamas.

high cycle 99 90%

three vessels were attacked in the strait of hormuz on july 7 — a qatari gas carrier, a saudi crude tanker, and a third ship — the largest single-day incident count since the june us-iran peace deal took effect. at least four tankers subsequently diverted away from the strait and the threat level was raised to severe. an escalation of this scale in the world's most important energy chokepoint, weeks after a peace deal, is structurally unusual.

high cycle 98 80%

a qatari lng tanker and a saudi crude tanker were attacked near the strait of hormuz with projectiles and a drone, pushing shipping threat level to severe and oil prices up 6%. the white house revoked iran's oil sale license in response, fracturing a us-iran detente. the strait carries a large share of global seaborne oil, so attacks there ripple outward quickly.

high cycle 97 90%

three commercial tankers, including a qatari lng carrier, were attacked near the strait of hormuz within a single 24-hour window, with suspected iranian missiles and drones as the cause. the joint maritime information center raised its threat level to severe and the us-iran ceasefire is now visibly undermined. roughly a fifth of the world's oil transits this strait; three strikes in one day is a structural escalation, not an incident.

high cycle 96 70%

taiwan accused china of deliberately damaging the undersea cable linking the island to the united states, and separate analysis framed undersea cables as a rising front in us-china competition. cutting a transpacific data link is a physical act with strategic reach, and attribution here is taiwan's claim rather than established fact.

high cycle 96 82%

a projectile hit the qatari lng tanker al rekayyat about eight nautical miles east of limah, oman — on or near the us-coordinated southern transit corridor that vessels have used since last month's ceasefire. no casualties, but a fire ignited and analysts say it may slow the return of qatari gas flows. striking the designated 'safe' corridor is what makes it structurally notable.

high cycle 95 85%

iran fired at least two missiles at commercial ships crossing the strait of hormuz on july 7, striking a qatari lng carrier near the omani coast and a second tanker that caught fire. this broke a memorandum of understanding signed less than three weeks earlier, and coincided with the expiry of a one-week us-iran agreement.

med cycle 95 75%

cuba's national grid fully disconnected on july 6, the third total blackout in six months, with the electricity deficit reaching 1,955 megawatts and daily outages averaging 20 hours amid fuel depletion. repeated nationwide grid collapse in a single country is a structural failure signal, not an isolated fault.

high cycle 94 85%

cuba's national electric grid collapsed entirely at midday, cutting power to roughly ten million people across the whole island — hospitals, transport, homes. this follows months of rolling blackouts tied to decaying plants and fuel scarcity; a full nationwide collapse is the failure mode a grid is designed never to reach, and cuba has now reached it repeatedly. same day, three major undersea cables off south africa were reported damaged simultaneously, forcing international traffic onto remaining routes.

low cycle 93 62%

the panama canal authority is again tightening maximum draught for neopanamax vessels, from 15.02m to 14.94m on july 24 and 14.78m on august 15, signaling a return of drought-driven capacity limits like the 2023-24 crisis. a recurrence of water-stress constraints on a chokepoint carrying much of global east-west trade is a slow structural pressure.

high cycle 92 82%

the strait of hormuz is closed, and vlcc tanker rates to enter the persian gulf hit $460k/day, more than four times the pre-disruption baseline. analysts describe a billion-barrel global oil inventory deficit that would take at least six months to restock. at least eight vessels including five supertankers exited the strait hugging the iranian coastline as among the last oil tankers to leave.

high cycle 92 70%

in a single window, subsea and terrestrial cables failed on three continents: venezuela's main submarine fibre ruptured after twin earthquakes, pakistan's sea-me-we 5 hit an undisclosed fault, guam saw a nine-hour connectivity drop of nearly 50% with no attribution, and a uk contractor severed fibre in maghull. several causes are unstated or unattributed. the clustering of independent physical-layer failures in one cycle is unusual.

high cycle 91 70%

planet labs restored four months of locked middle east satellite imagery archives that had been held under a government-requested 'shutter control', reopening retroactive conflict-theater imagery to open-source analysts. in the same window, six tankers rerouted along the omani coast after unexplained reversals in the us-protected hormuz corridor, transponders often off. the quiet rollback of an imagery embargo alongside anomalous vessel behavior points at a conflict theater becoming legible again.

med cycle 90 85%

maersk suspended all transshipment through djibouti's port of doraleh over red sea attacks, stretching delivery cycles from 28 to 52 days with rising war-risk surcharges; meanwhile starlink deactivated thousands of terminals in resistance-held myanmar during a cyber-scam crackdown, cutting connectivity for civilians and fighters alike. two chokepoints — one maritime, one orbital — narrowed in the same week, each controlled by a single company's decision.

med cycle 89 75%

oil tankers in the strait of hormuz performed unexplained u-turns and shifted to the oman-side route despite a us-protected corridor, while a cargo vessel was attacked by armed assailants 30 nautical miles off hodeidah, yemen. separately, congestion at jeddah port is straining the overland alternative. the world's key oil chokepoints are all showing stress at once, even as india reports fertilizer shipments transiting hormuz safely — nervous behavior without a declared cause.

med cycle 88 60%

hormuz strait traffic remains fragmented at roughly 85 percent below the pre-war baseline of 130-140 daily crossings; vessels shifted to an iran-designated route after irgc warnings on july 5, then partly resumed the omani corridor a day later. a cargo vessel was also attacked ~55km southwest of hodeidah in the red sea, the bypass route now carrying middle east oil. the inconsistent rerouting suggests tactical improvisation by shippers rather than any resolution.

med cycle 88 65%

russian forces located and destroyed 60+ ukrainian starlink terminals in the kharkov region during june using fpv drones, reportedly finding them via poor camouflage, disrupting frontline troop communications. separately a july 5 strike hit two electrical substations in occupied crimea, where year-over-year satellite imagery shows persistent decline in nighttime lighting. physical targeting of satellite-comms hardware is a deliberate move against the space-linked layer of the war.

med cycle 87 60%

at least five vessels aborted strait of hormuz transits with sharp u-turns and others rerouted toward the oman coast, while iran reportedly maintains minefields and refuses a demining commitment agreed in a june 17 memorandum. a cargo vessel was attacked near hodeidah despite the ceasefire. the friction persists structurally even though india rolled back its emergency gas curbs as lng shipments resumed.
