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.
