At first, we didn’t think there was a substantial issue - the power in James college was knocked out for about a second, but their UPS coped so we assumed ours would too. Some amusement was poked at YSTV for neglecting to put their web/db server on said UPS. Once we confirmed our website was inaccessible, we made our way over to investigate, but assumed v1rs0 was just rebooting.

We reached URY in a state of running on UPS power, so started a graceful shutdown of all servers using ACPI (i.e. the power button). We left logger2 running at this stage because of the uptime, and logger2 is a hardy-ish device that’s seen a lot anyway. Everything but that was powered down by 01:52.

The B16 breaker that estates told me they would upgrade to C16 last year tripped from the sudden desire of a large quantity of batteries to charge up. Turning the power back on caused a happy bright flash, some dimmed lights, then the breaker re-tripping.

Luckily, switching off the compressors and distribution amplifier for the audio path was sufficient, and the UPS then began to charge at 05:44, and enabled server power at 05:49.

As is traditional, logger2 decided not to play ball when we powered it up. It made strange noises and smelled a bit, so we left it off overnight. Confirmation that logger1 and uryblue were operating left us happy to power the transmitter on by 06:30. It did start up later in the day, so was probably just being fussy because it was a bit cold.
