Earthquake tripped ETMY SWWDs

Starting at 23:47 Sun-19Jul2026-PDT the ETMY test mass was rung up by an earthquake. Both SEI and SUS had both tripped at 00:02 Mon-20Jul2026-PDT. The ETMY HWWD counted down to 7 mins before resetting.

At 06:45 I untripped the SWWDs. The user model WDs remain tripped.
