To answer the first part of your question, Pine, Daniel's email was sent at
01:52 UTC on the 22nd. So tomorrow would refer to 00:00 on the 23rd.

Hi, thanks for the notice. Can you specify whether
"tomorrow" refers to 22
May UTC or 23 May UTC, and how long the maintenance window is likely to be?
Some of us may want to read or write a Phabricator
<strike>complaint</strike> task during the maintenance window, and if we
know when to expect Phabricator may be temporarily unavailable then we can
plan accordingly.

Tomorrow we have planned a major upgrade of the
Phabricator prod server.
Starting from around 00:00 UTC (after Evening SWAT) we want to switch
from
phab1001 to phab1003 as the production server.
This will involve:
- switching from jessie to stretch
- switching from mod_php to php-fpm
- switching from PHP 5 to PHP 7.2
- upgrading apache from 2.4.10 to 2.4.25
We are also hoping it will finally fix the httpd memory leaks we have
been
seeing on the current server for a long time and
which require periodic
service restarts.
In case we run into any unexpected issue we will simply fall back to
phab1001
and keep running as before.
