(I have the impression that our maintenance notices are not always very clear, since people are sometimes surprised when we carry out previously-announced maintenance. So, here's a new and hopefully improved notification format.)
This is a maintenance notification for tonight (Saturday 11th) UTC. The following services will be affected:
Service | Expected impact - --------------------------------+----------------------------------- s1 cluster | User databases unavailable for < 10 minutes s2 cluster | Entire cluster unavailable for < 10 minutes s3 cluster | User databases unavailable for < 10 minutes s4 cluster | User databases unavailable for < 10 minutes s5 cluster | Entire cluster unavailable for < 10 minutes s6 cluster | User databases unavailable for < 10 minutes user databases (sql) | Unavailable for < 10 minutes user-store filesystem | Unavailable for < 20 minutes NFS, LDAP, misc services: | None expected, but at risk during maintenance. SVN, phpMyAdmin, SGE, tsbot, | mail forwarding, DNS, | sql-toolserver database | All other services | No impact
Start time: Sunday, 12th September, 12AM UTC End time: Sunday, 12th September, 3AM UTC
Details:
Tonight we will complete the upgrade to Solaris 10 Update 9 on the remaining servers. This requires under 10 minutes downtime while each system reboots.
Since we will be upgrading the primary server in each cluster, which holds user databases, these will be unavailable during the reboot. Access to replicated databases will not be interrupted, since queries will be directed to the alternative server while one is rebooted.
The exception is s2/s5 and sql (user databases), which currently have only one server. They will therefore be unavailable during the reboot.
- river.
Thanks River,
Though I personally have no problem with your previous announcement about the maintenance yesterday, but this table-like notice is much beter in my opinion.

I would agree too, the format looks more verbose! :)
Thanks River!
