We will be performing site wide maintenance on Monday, October 23rd, 2017 at 10:00am EDT (14:00 UTC). This maintenance is expected to last 15 minutes. During this window, the UI and API will be unavailable as we fail over to a new primary datacenter. This maintenance also includes the promotion of a new primary DB and movement of alerting services.
Over the past few weeks, we have spun up data collection to this new DC, and have been serving graph, worksheet, and dashboard data from it. During the maintenance window, data collection will continue uninterrupted. There will be an alerting outage as we switch services to their new home. Alerts that would have fired in the window will fire when we come out of maintenance; alerts that would have cleared will clear when we come out of maintenance.
Please double check that our IPs listed in out.circonus.net are permitted through any firewalls, especially if you have rules to permit webhook notifications.
We expect no major issues with this move. If you have any questions, please contact our support at firstname.lastname@example.org for further clarification.
