We are working on these issues and will update this post when we have more information.

Update (10:30am): everything is back up.

As of 10:45am EST, we are experiencing trouble with our network infrastructure.

UPDATE: As of 11:35am, EST, we believe everything is back to normal.

On Tuesday, February 27, 2007, we will have a scheduled downtime from 4:00am to 8:00am EST.

Planned maintenance includes:

This work will bring our infrastructure up-to-date with current software and firmware. Among the patches are support for the new start of Daylight Savings Time which will begin March 11th this year.
