Greetings Spark Users! Announcement!
In the never-ending journey to massive scale for systems, another milestone has arrived! On Tuesday night we’ll be upgrading our database to a clustered deployment with clean failover. The impact will be minimal, but I wanted to give everyone a heads-up.
Beginning at approximately midnight in Minneapolis (10pm Tuesday June 4 in San Francisco, 1am Wednesday June 5 in New York, 5am UTC, 6am in London, 1pm Wednesday in China) we will take the web IDE down and put up a maintenance page. If everything goes smoothly, we expect the web IDE to be down for about 10 minutes.
The Device Service and api.spark.io will continue to function normally throughout the transition, however, a small number of database writes during the transition may not transfer to the new system. If you happen to claim or rename a Core via the API (including the mobile app or the CLI) during the maintenance window, you may have to claim/rename it again when everything’s up and running on the new system.
When we restart the Device Service and point it at the new database, any Cores you have online will drop and immediately reestablish their connection to the Spark Cloud. If you blink, you’ll miss it.
Don’t hesitate to let us know if you have any questions or concerns. @jgoggins and I will be on point during the transition. I’ll post here when everything’s back to normal.
Cheers, and may the be with you!
