Our data center has noticed a problem with a patch panel cable. In order to fully repair the problem and replace the cable they have scheduled emergency maintenance for the Houston data center.
While the expected the impact of the cable replacement is to be in seconds, an hour maintenance window has been scheduled to allow for monitoring.
Servers possibly affected by the maintenance: dweb1-47 and web28-83.
[Update 1:07CDT/6:07UTC]: The maintenance window is over.
