A last thing that wasn't working was the wiki. Now fixed:
So we can consider migrating to phantom (the new server) really
soon now. This will obviously disrupt the services during the
migration, for a duration that will depend on DNS propagation.
- shutdown all services on spectre
- dump all PostgreSQL databases
- rsync everything a last time from spectre to phantom
- reimport all PostgreSQL databases
- startup all services on phantom
Executing these steps should roughly take an hour, given that
data have been rsync'd every 2 hours since weeks. But as said,
DNS propagation will make the disruption longer for people still
trying to reach spectre. This can be mitigated to some degree
by reducing the TTL of the records.
Unless I oversaw something, migrating over the next days should
be an appropriate time.

- Wiki::Toolkit 0.75 is the last version compatible with the
current schema used by Act. It should be possible to upgrade
the schema to newer version, but this will be tried after
migrating to the new server.
Close the world, txEn eht nepO.
