We will have a scheduled maintenance window tonight from 7pm to 11:00pm
PDT. The following changes will take place:

* 7:00pm PDT (0200 UTC) support.mozilla.com updates. We’ll be updating
support.mozilla.com to pick up recent security and code updates. No
downtime is expected.

Please let me know if you have any reason why we should not proceed with
the planned maintenance. As always, we aim to keep downtime to as little
as possible, but unexpected complications can arise causing longer
downtime periods than expected. All systems should be operational by the
end of the maintenance window.

We will have a scheduled maintenance window tonight from 7pm to 11:00pm
PDT. This is being tracked in master bug 449397. The following changes
will take place:

* 7:00pm PDT (0200 UTC) wiki.mozilla.org updates. We’ll be moving
wiki.mozilla.org completely behind SSL. No downtime is expected.

* 7:00pm PDT (0200 UTC) www.mozilla.org DNS change. We’ll be offloading
www.mozilla.org to a CDN and pushing a DNS change to make that active.
No downtime is expected.

* 8:00pm PDT (0300 UTC) bugzilla.mozilla.org database work. Bugzilla
will be down or slow while we pull out some data to fix an issue related
to the Bugzilla reorganization. Duration 30 minutes.

Please let me know if you have any reason why we should not proceed with
the planned maintenance. As always, we aim to keep downtime to as little
as possible, but unexpected complications can arise causing longer
downtime periods than expected. All systems should be operational by the
end of the maintenance window.

As mentioned, this maintenance window is tracked in bug 449397. Feel
free to comment directly in that bug if you see issues past the planned
downtime.

(Apologies for the short notice. We generally want to stick to our
normal advertised maintenance windows but sometimes technology works
against us.)

We will have an emergency maintenance window tonight from 6pm to 11:00pm
PST.

The following work will take place:

* 6:00pm PST (0200 UTC) ) EqualLogic storage array firmware upgrade.
See bug 464458 for details. We’ll be locking the tree to all check-ins
at 5:00 PST tonight to start the maintenance window and will unlock it
once the machines have come back up and gone green for a cycle.

Last night one of our network attached storage devices experienced an
error and didn’t fail over properly. The effect was such that we had to
close the tree as Tinderbox wasn’t getting proper data for updates, and
we couldn’t tell what was happening with our builds. While we were able
to restore that functionality, there is a high chance that any of our
VMs attached to this storage device may experience further problems.

To fix this, we’ll need to pause all of our VM systems (most notably
build machines & unit test machines, but also litmus and some others)
for a few hours. The affected systems would be:

fxdbug-win32-tbox
fx-win32-1.9-slave2

After discussing this with the sheriff, product leads and release
engineering team, we’ve decided it would be best to do this as soon as
possible. We’ll be locking the tree to all checkins at 5:00pm PST
tonight to start the maintenance window, and we’ll unlock it once the
machines have come back up and gone green for a cycle. Vlad will try to
shepherd the remaining patches for beta 2 blockers that are in the
checkin queue before 5pm, but at that time we’ll stop all work and pick
it up tomorrow morning.

Let us know if there are any objections as soon as possible.

At around 5:07am PST this morning, Mozilla’s primary datacenter
suffered an approximately 13 minute outage.

Mozilla uses Cisco Firewall Service Modules in the core Cisco 6509
switches. At about 5:07am the primary unit failed and appears to have
crashed within the failover code. This caused an incomplete failover
and the standby FWSM never assumed full control.

At 5:19am PST the primary FWSM was manually reset which allowed the
standby to complete its failover.

We have grabbed crashinfo and are working with Cisco TAC to diagnose.
Specific details will be tracked in bug 528186.

We apologize for any inconvenience this may have caused and will
continue to work with Cisco on a remedy.

We’ll be taking advantage of the end-of-holiday lull and post-Fennec
1.0rc1 / pre-Firefox 3.6 releases to perform maintenance on some
Production & Release Engineering infrastructure.

During this window, all check-in trees will be closed.

We’ll be performing maintenance Sunday from 12:00pm to 6:00pm PST .

The following changes will take place:

* 12:00pm PST (2000 GMT) Duration 2 hours: NetApp OS upgrade. We’ll be
updating the two Network Appliance file servers that handle a number
of Release Engineering VMs. See bug 531233 for more details.

* 12:00pm PST (2000 GMT) Duration 2 hours: b01 database cluster
maintenance. We’ll be upgrading the firmware on the b01 database
cluster (bug 535859) and performing maintenance to clear up disk space
(bug 528573). This work will affect the following services:
developer.mozilla.org / MDC
litmus.mozilla.org
bonsai.mozilla.org
• ViewVC for SVN

* 1:00pm PST (2100 GMT) Duration 4 hours: ESX hardware upgrade. We’ll
be upgrading the production ESX cluster from old dual CPU HP DL385
servers to our standard 8-core/32GB RAM HP BL460 platform. Since this
upgrade involves switching CPU platforms (AMD to Intel), it requires
each VM to be shutdown, migrated and powered up. Each VM’s downtime
will be not unlike a normal reboot.The following list includes notable
VMs & services that will be briefly affected:
mpt-vpn.mozilla.com
graphs-stage.mozilla.org
support.mozilla.com Live Chat
hacks.mozilla.org
quality.mozilla.org
build-graphs.mozilla.org
• All Build, unittest, Talos and TryServer systems

While the ESX work is from 1-5, note that the downtime is from 12-6.
This is to give us time to power down the all the RelEng systems, as
well as spin them all back up and verify they are running "green" before
reopening the trees.

We will have a scheduled maintenance window tonight from 7:00pm to

* 7:00pm – Upgrade the server ‘mradm01′ from RHEL4 to RHEL5 (bug
542454). Actual downtime is expected to be 30 minutes or less, but it
may take through the end of the window to get all services completely
functional again afterwards. This server hosts ns1.mozilla.org (DNS
server) and the nagios slave (facility-wide system monitoring) for the
MPT colo facility. DNS services are redundant (ns2 and ns3 will pick up
the slack). We will be without monitoring in the MPT colo facility
while the server is being upgraded, however. This means any problems
that are normally automatically detected and cause the oncall sysadmin
to get paged will not be detected or paged about during the outage. We
ask that if anyone observes any such problems during the window that you
report them in the #bmo channel on irc.mozilla.org (click the following

I don't normally post about Scheduled Downtime weeks in advance but we've scheduled a fairly intrusive upgrade in a couple weeks on Saturday, April 17 @ 2pm (https://bugzilla.mozilla.org/show_bug.cgi?id=502151).

We'll be doing OS & firmware upgrades on our NetApp cluster that requires physical reboots of the disk array shelves. Unlike most NetApp OS upgrades, this will take a number of services offline.

We plan to manually failover a number of production services to the Phoenix data center during the week of April 12, however, this work will close all check-in trees.

I'll post a reminder as we get close to the date.

I've blogged with more details @

Reminder: we have a scheduled maintenance window this Saturday @ 2pm. More details can be found here[1].

We will have a scheduled maintenance window tonight from 9:00pm to 11:00pm PDT. The following changes will take place:

* 9:00pm PST (0400 UTC) addons.mozilla.org primary site move. In preparation for Saturday’s scheduled downtime, we’ll be manually failing addons.mozilla.org to Phoenix. We’ll need to take the site offline for a bit to do a final content sync. Duration 30 minutes.

Please let me know if you have any reason why we should not proceed with this planned maintenance. As always, we aim to keep downtime to as little as possible, but unexpected complications can arise causing longer downtime periods than expected. All systems should be operational by the end of the maintenance window.

Feel free to comment directly if you see issues past the planned downtime.
