We will have a scheduled maintenance window tonight from 7:00pm to 11:00pm PST. The following changes will take place:
- 7:00pm PST (0300 UTC)
mpt-vpn.mozilla.comVPN configuration change. We’ll be restarting OpenVPN to pick up some configuration changes. Any existing VPN connections will be dropped. Duration 5 minutes.
- 7:00pm PST (0300 UTC) Level3 BGP turnup. We’ll be turning up transit peering with Level3. No downtime expected.
- 7:00pm PST (0300 UTC) MySQL slave database configuration change. We’ll be making a runtime change to all MySQL slave databases to ensure they are read-only. See bug 477099 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 in those bugs (or this blog) if you see issues past the planned downtime.
