Scheduled tor2 network maintenance - 04-Dec-2015

Post by porcupine »

Hi Folks,

Please be advised of the following maintenance window:

Maintenance Window: Friday December 4th, 10:00pm - 8:00am Eastern Time.
Facility: Tor2
Affected Device(s): core03.tor2, core04.tor2, dist03.tor2, dist04.tor2
Affected Customers: Tor2 facility customers
Service Impacting: Yes - Customers should expect intermittent connectivity issues, specifically in terms of connectivity between the tor1 and tor2 IP space.

Details: We will be performing follow-up testing/troubleshooting, with regards to the previous maintenance window on 19-Nov-2015. Unfortunately during the previous maintenance window, we were unable to reproduce the routing anomaly experienced during the 30-Oct-2015 outage, which appears to occur intermittently when the RBS transport circuit is offline.

We have scheduled a longer maintenance window for this event, and will shut down the RBS transport circuit from the TOR1 facility side, in an effort to reproduce the routing anomaly. We have scheduled a 10 hour window for this event, given the previous 4 hour window was inadequate. We anticipate the actual disruption from this activity to be limited to one or two short outages, primarily impacting routing between the facilities, same as before. We will attempt to minimize impact during this event, however some disruption should be expected due to the nature of this maintenance.

Customers in the tor1 facility will not be impacted by this maintenance (aside from impacted connectivity to servers in the tor2 facility).

Regards,
Myles Loosley-Millman
