Scheduled maintenance to migrate GTT (formerly nLayer) link over to the new core router. This maintenance was originally planned for two weeks ago but was postponed.
Date: Sunday, July 28th 2013
Start Time: 12:00 AM CDT (GMT-5)
End Time: 2:00 AM CDT (GMT-5)
Maintenance Scope: admin down the GTT link on core router "core1.chi02", then physically move the link to the new core router "core3.chi02" and bring it back online in a controlled manner.
Customer Impact: we expect the customer impact of this maintenance to be minimal, though some brief periods of suboptimal routing may occur.
While the work itself may only take a few minutes of configuration, but extra time is allowed for extensive testing to ensure that no further issues will occur.
If you have any questions regarding this maintenance, please feel free to contact us in response to this email at email@example.com
