Anyone I host, either at or on their own domain, needs to be aware of this alert from our hosting provider Dreamhost: they’re physically relocating the servers this Friday/Saturday. There’ll be a roughly five-hour outage early Saturday morning, UK-time, affecting web and mail.

You shouldn’t lose mail in the process – it’ll just spool up on their servers waiting to be delivered – but if you see some weirdness, this will be why. Your websites will be down and unavailable. You’ll likely also be unable to send email during the downtime.
