過失 When We Are At Fault
The thirty-one minutes at Hong Kong.
One incident deserves more than a row. On 11 July an automated prefix-list rebuild withdrew HKG-1 from three of our four transit partners. The timeline below is the one kept during the event, not one reconstructed afterwards. We publish these whether or not anyone noticed and whether or not the SLA was breached, with the cause named rather than described as an unforeseen condition. Credits are applied without a ticket. If a postmortem here ever reads as though nothing could have been done differently, it is a bad postmortem, and we would rather be told so.

Sits on the ink band as a plain .tbl — page.css already restyles thead, rules and .num for .on-ink. Times are the operator log, unedited; the 12 Jul row is the only one added after the fact and is dated rather than timed.
