We're doing a system infrastructure upgrade this weekend. We are planning on just a few minutes of downtime for this upgrade and some latency while we verify connectivity and failover traffic from secondary to the primary firewall. This will happen between 1:00 a.m. and 5:00 a.m. Saturday, January 7th as reported on our system status RSS feed.

Bill has more information on his blog, if you're interested. We’ll also be publishing more details on our latest infrastructure moves very soon.
