[sf-lug] scheduled sites outage TOMORROW: [*.]sf-lug.{org, com}, [*.]balug.org, ... >=2017-09-26T09-0700-->~=2017-09-26T15-0700

[Michael Paoli]

As mentioned earlier
we're anticipating a scheduled sites outage tomorrow,
sometime between 9:00 AM and approximately 3:00 PM. PDT.

details/references:
outage window: >=2017-09-26T09:00:00-0700-->~=2017-09-26T15:00:00-0700
reason: scheduled utility power outage
site(s):
     sf-lug.{org,com}  - everything on/under those domains
     (does NOT include SF-LUG lists (hosted on linuxmafia.com))
     balug.org - everything on/under that domain
mitigations/controls:
Don't have operational UPS presently (even if I did, it probably
wouldn't suffice for potential duration of outage).  The impacted sites
mentioned above are on virtual machine.  Prior to outage, I'll (live)
migrate that virtual machine onto physical machine that should be able
to restart okay after drop of and restoration of power, and likewise
virtual machine thereupon should automatically be restarted and recover
fine too.  With journaling filesystems and such, hopefully this will
limit the outage to not much longer than the utility power outage
itself.  Even in "worst case", I expect sometime tomorrow after 3pm,
should some manual intervention be needed, to have the sites up later in
that day - I'll also have fresh image on another machine that won't be
powering up/down with the utility power, so in all cases, the sites
either will come back up, or I'll be able to bring it back up without
too much difficulty.
