On Saturday, July 9, 2011, starting at 11:00pm PDT (July 10, 06:00 UTC) and lasting for up to three hours, we will be upgrading both our internet connection uplinks, and several inter-switch cross-connects in our primary data center.  As all of the links which are going to be upgraded are already redundant, except for a few brief pauses on the network as Spanning Tree reconverges after an uplink is changed, we expect this maintenance to have no significant impact on our customers or their running applications.  However, as is the nature of any maintenance on the physical connections to our core routing infrastructure, an increased risk of an outage exists.

UPDATE, 11:30am PDT (05:30pm UTC): In the next hour, we’ll begin the process of upgrading one of our inter-switch cross-connects in order to resolve an unexpected network issue. This work should be complete no later than 2:00pm PDT.
