[fdo] Mail outage last night

[Daniel Stone]

Hi all,
Last night, around 6pm UK, the machine hosting gabe.fd.o, our main
SMTP and list transit, suffered a hard physical disk failure.

This resulted in us failing safely - bouncing all incoming mail with
SMTP errors, ensuring it should have been redelivered, albeit very
noisily as everyone got a lot of bounce messages.

We have migrated gabe to another physical host to keep email moving
whilst we come up with a long-term fix. We have ordered a couple of
replacement disks, which will require some downtime for the following
hosts when it arrives and we can replace it:
  - annarchy.fd.o (www.fd.o, www.x.org, all project web pages apart
from GitLab Pages)
  - culpepper.fd.o (bugs.fd.o)
  - ray.fd.o (database for bugs.fd.o)
  - emeril.fd.o (patchwork.fd.o, members.x.org)
  - fruit.fd.o (LDAP accounts)
  - patrick.fd.o (misc admin utilities)
  - roastbeef.fd.o (decommissioned: was phab.fd.o and jenkins.fd.o)

We'll notify closer to the time when we're having this downtime.

Huge thanks to Tollef for dealing with this so far.

Cheers,
Daniel
