In order to expand capacity and to provide better mailing list
deliverability to email providers using DMARC , we will be
performing service-affecting maintenance on the Ubuntu mailing
lists server, starting from 00:00 UTC next Monday, 2017-09-04. We
anticipate this maintenance to take no longer than 6 hours.
During the downtime, there will be no emails delivered on Ubuntu
mailing lists. All other Canonical-managed Ubuntu services should
remain up and be unaffected.
Progress of the work will be communicated in #canonical-sysadmins
on Freenode IRC. If you have any questions or concerns please
contact the Vanguard mentioned in the #canonical-sysadmins channel
topic and quote ticket uRT#30108.
Mailing list moderators, please notify your respective lists of
this maintenance as necessary.
