Xen Project {lists,mail,downloads} outage, 22 April

[Ian Jackson <ian.jackson@xxxxxxxxxx>]

Our listserver and mailserver are going to be updated to current
Debian stable on Wednesday the 22nd of April.  The outage window is
0600-0900 UTC, but we hope not to use all of it.

During this time we expect that mail will be delayed, but hopefully
not lost or rejected.

The mailing list management UI may be unavailable.  We recommend that
even if it appears to be available, you should defer your list
(un)subscriptions until after the outage window.  It is possible that
if things don't go well, changes made during the outage window might
be rolled back.

The Xen release downloads (served from downloads.xenproject.org) will
also be unavailable during the upgrade.

Mail sent via xenbits will be affected, since xenbits sends outgoing
mail via mail.xenproject.org.  But access to git repositories
(xenbits.xenproject.org), and the osstest CI
(test-lab.xenproject.org), should be unaffected.

Ian.
