We regularly upgrade and backup systems nightly and most often with no known impact to the network, servers or portals. If a Geo Datacenter is impacted (Vancouver, Calgary, Ottawa or Montreal), we will automatically fail over prior to the maintenance to ensure calls are not impacted.

We are investigating Issues with the Our Calgary Datacenter.

Rogers Calgary 3 ISP LoS Loss of Internet Service for Calgary 3 Colocation Customers Rogers Data Centres Network Services Duration: 1 hours 22 minutes

Executive Summary: CR 27797, a scheduled reboot for routers RTR1A and RTR1B in Calgary 1 was performed during customer announced maintenance window from 06:00h to 08:00h Eastern to remediate high memory utilization.

Services that may observe increased latency or momentary packet loss 2 times for less than 5 minutes during maintenance window included Colocation ISP in Calgary 1, Calgary 2, Calgary 3, Edmonton 2 and VPC service in Calgary 3.

RTR1A and RTR1B were rebooted in sequence. Test of OSPF and BGP protocol status, IP routes and traffic levels before and after the reload were consistent in the rebooted devices. Service Assurance became aware of LoS of ISP in Calgary 3, escalating to MT 50649 at 07:21h. RDC- Network Service was contacted at 07:28h.

Problem was determined to be due to an OSPF protocol issue in Calgary 3 preventing IP blocks in Calgary 3 from being installed into the routing table. OSPF in Edmonton 2, Calgary 2 and Calgary 1 continued to operate nominally.

Calgary 3 OSPF was administratively forced to re-form the routing table by removing CLGRABD3YR01 and CLGRABD3YR02 from performing the role of Designated Router (DR), restoring service.
