What: Rackspace will be performing a database reconfiguration for the underlying tracking database that services HEAT in the public cloud. The Linux Foundation will also take this time to perform some outstanding systems maintenance related to SSL certificates and the managed hardware firewall.
When: Friday, June 30 @ 17:00 - 19:00 PDT (2017-07-01 00:00 - 02:00 UTC) Why: Rackspace has informed us that they need to perform fixes to the underlying database that stores information about HEAT resources. As we are apparently one of, if not the, heaviest user of HEAT in their environment they requested a service window where we could pause our systems so as to not cause major failures in our jobs. Additionally, there is some outstanding work to transition our systems that are using Let's Encrypt certificates (everything but Nexus) to fully automated configurations. This work will cause the sites to disappear temporarily as we turn the automation on and it starts processing components properly. Once the automation is in place we should not see any further disruptions as certificates are automatically updated. Finally, there is an outstanding reboot on the hardware firewall that Rackspace has in front of our private cloud. This reboot needs to be performed to bring the system up to date on the latest firmware. Impact: All jobs will be paused. Jobs that are running will be left to continue running as the work that is being performed should not impact running jobs. Internet access to resources will be unavailable for a few brief outages as the firewall is reboot and as the certificates are transitioning to automated management. Notices will be posted to the mailing lists and in #opendaylight on Freenode at the start and end of the maintenance. If you have any questions or concerns please raise them now! -Andy- -- Andrew J Grimberg Lead, IT Release Engineering The Linux Foundation
