On Sunday, December 29th at 1pm PST, (2pm AZ, 4pm EST, 9pm UK, 10pm CET) we’re going to swap out our network switch. During this time all MusicBrainz sites hosted in California will be unavailable. (that is all sites, save for the primary and secondary FTP mirrors and the FreeDB gateway).
The work will not start exactly at 1pm, but we’re doing to start executing our plan at 1pm. The exact time for the outage will be announced via Twitter and via the banner on musicbrainz.org
We hope that this outage will last only 10-15 minutes, but as these things typically go, you’ll never know how long it will really take.
Sorry for the inconvenience.
