There's upcoming scheduled sites outage due to some scheduled electric utility work.
Scheduled outage window:
=2017-09-26T09:00:00-0700-->~=2017-09-26T15:00:00-0700
sites impacted: [*.]balug.org (note that it may or may not impact www.balug.org and balug.org - depending where they are at that time, but will impact at least all other *.balug.org sites/domains)
[*.]sf-lug.{org,com} (note that SF-LUG list isn't impacted)
To the extent feasible, I'll try to minimize the outage time, but expect it may minimally be up to fair part of an hour, and "worst case" might be 6 hours or more (notably also if I can have things automagically recover easily enough unattended upon power restoration - or not).
It's also possible this outage may be delayed or rescheduled (notably depending what electric utility provider gets up to).
