We're currently investigating reports of slower than usual response times. Our engineering team is actively working to identify the cause and will post an update here as soon as we have more information.
- identified Sep 17, 2026, 10:06 AM UTC
We've identified the cause of the performance issue and are rolling it out across the platform. Performance has been restored for some customers, and we're continuing to apply the fix to the remaining servers. As part of this, the Checkpoint module has been temporarily disabled. We'll post another update as more customers are restored.

We've identified the cause of the performance issue and are rolling out a fix across the platform. Performance has already improved for some customers, and we're continuing to apply the fix to the remaining servers. As part of this, checkpoint has been temporarily disabled. We'll post another update as performance is restored for more customers.
- monitoring Sep 17, 2026, 10:43 AM UTC
Performance has been restored across the platform following the steps we've taken today. We've identified a permanent fix, which we'll deploy outside core hours tonight and which will re-enable Checkpoint for those customers using it. We don't expect this to affect performance further, and will confirm once it's complete.
- monitoring Sep 17, 2026, 05:34 PM UTC
Platform performance remains normal. Checkpoint remains temporarily disabled while we prepare tonight's fix, and will be re-enabled once it's deployed. We'll confirm here once that's complete.
- resolved Sep 17, 2026, 07:12 PM UTC
Tonight's fix has been deployed and Checkpoint is now re-enabled. Platform performance remains normal and everything is working as expected.
