This is a reminder about the network maintenance we will be performing July 11, 2008 starting at 10pm Pacific time. All of DreamHost will be inaccessible during this downtime, including email, websites, jabber, streaming, mysql, etc. No data will be lost during this time, and email will be deferred until the network is back online and delivered over the course of the night by the sending servers.
