DC Network Maintenance Window
Scheduled a maintenance window in order to perform firmware updates on several pairs of core network switches which transit traffic within our facility. Working with Cisco, we have identified major flaws in the firmware running on the affected Nexus 9300/9500 switches and Cisco has advised that a firmware update is necessary to resolve the issues. The software flaws affecting these switches results in unpredictable routing behavior, so it is possible that during the maintenance while we shift traffic off the affected switches to perform the upgrade, there may be a brief 5-10 minute period of intermittent packet loss or additional latency. We are doing everything we can to minimize this possibility, and we hope to keep customer impact to an absolute minimum. The maintenance window to perform this work has been scheduled for Friday, June 12th, 2015 from 10:30 AM to 4:30 PM IST.
10:30 AM IST We are beginning to shift traffic to the redundant core to begin this maintenance
1:24 PM IST This maintenance is now complete. Please contact support if you have any issues accessing your servers at this time.
