Since our last update, we have begun gradually resuming work, and some queued workflows and jobs are starting again. Most queued work is still waiting, and jobs that do start may have waited over an hour. We are increasing the rate carefully to avoid overloading our systems. Delayed updates continue to appear in the CircleCI UI and API.
Please continue to avoid retriggering pipelines or workflows, as this may create duplicates as queued work resumes.
We will provide another update by 23:00 UTC.

Update
Since our last update, most of the pipelines that were delayed earlier in the incident have now been processed, and their workflows are queued to start. New workflows and jobs remain paused while we prepare to resume work safely. Delayed updates continue to appear in the CircleCI UI and API.
Please continue to avoid retriggering pipelines or workflows, as this may create duplicates once work resumes.
We will provide another update by 22:30 UTC.

Update
Since about 20:48 UTC, new workflows and jobs are not starting. We have temporarily paused starting new work so that our systems can catch up on work already in progress, including delayed updates to the CircleCI UI and API. Older updates are now appearing in the UI and API as this backlog clears. New pipelines are still being accepted and queued
Please avoid retriggering pipelines or workflows during this time, as this may create duplicates once work resumes.
We will provide another update by 22:00 UTC.

Update
Jobs are starting faster and fewer are failing: most jobs are now starting within about 4 minutes, down from about 6 minutes, and the longest waits have dropped from about 30 minutes to about 20 minutes.
Pipelines from earlier in the incident are now being worked through.
The CircleCI UI is still behind, and some older updates may take longer to appear. Jobs may already have run even if the UI does not show them yet, so please avoid retriggering workflows that don't appear in the UI.

What's changed since our last update
* The CircleCI UI is about an hour behind, and up to about 90 minutes for some updates. Workflows and jobs may already have run, or may be running, even if the UI shows them as not started or does not show them at all. * Jobs that are running are starting faster. Most are now starting within about 15 minutes, down from about 28 minutes, though some are still waiting over an hour. * New pipelines are increasingly delayed. * Some workflows are still failing. Workflows that could not be processed in time are being marked as failed. * Please avoid retriggering workflows that don't yet appear in the UI, as this may create duplicates.

Since 11:15 UTC, customers have experienced disruption to pipelines and notifications. Between 11:15 UTC and about 13:00 UTC, pipelines were created but not processed, and outbound webhooks and transactional notifications (Slack and email) were not sent. Between about 13:00 UTC and 14:40 UTC, workflows and jobs started with delays while we worked through the backlog. Since about 15:15 UTC, workflows and jobs have again been starting with delays.
What’s impacted Customers triggering pipelines and running workflows and jobs, customers viewing pipelines, workflows and jobs in the CircleCI UI, and customers viewing usage data on the Project Usage page.
What to expect - Since about 17:00 UTC, we are seeing an increase in delays. Most jobs are now taking about 25 minutes to start, and some are waiting up to about an hour. - Since about 17:15 UTC, some in-progress workflows have failed and a small number of jobs are failing to start. - New pipelines are being queued and are taking longer to start. - The CircleCI UI is more than an hour behind. New workflows and status changes may take that long to appear. - Please avoid retriggering workflows that don't yet appear in the UI, as this may create duplicates. - Usage charge data on the Project Usage page is currently stale.
