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) addons.mozilla.org DNS change. As part of our CDN trial/test, we’ll be offloading addons.mozilla.org to CDNetworks and pushing a DNS change to make that active. See bug 450745 for details. No downtime is expected.

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.
