Incident History
May 2026
Increased latency for large projects
Started: May 18, 4:41 PM
monitoring
We've cleared the backlog of background jobs for larger projects from our heavy project queues, with the exception of nine projects whose volume continues to exceed our daily fair use thresholds. Those nine have been redirected to secondary and tertiary queues that drain only after the primary queue is clear. Most of their jobs have now been processed, but a few projects generate more jobs than a normal day + overnight cycle can drain, so some backlog remains. We're continuing to work those q...

monitoring
We are continuing to monitor for any further issues.
May 25, 8:06 PM
monitoring
We continue to monitor background processing queues for larger repos (5K+ files), as we continue offloading incoming jobs from the outlier repos whose volume led to the original backlog. If you think you may have been paused as one of these repos with outlier-level volume, please reach out to us at support@coveralls.io and we'll confirm status and get you an ETA on when your remaining jobs will be processed.
May 21, 4:23 PM
monitoring
We have moved all repos with more than 300 jobs in queue to dedicated queues for processing. These 7 repos were responsible for 75% traffic in our heavy repos queue. This move allows us to provide normal processing times for non-outlier repos and dedicated resources to outlier repos. Outlier repos by their job volume will still take longer to clear. If you believe you may be one of these outlier repos, please reach out and we'll confirm and give you an idea of when your jobs will be processed...

We are keeping this incident open as we continue monitoring.
May 20, 1:48 PM
monitoring
We are still receiving reports of latency for large projects and are seeing backlogs of background jobs in queues dedicated to large repos (5K+ source files). We may pause some outlier repos with excessive numbers of jobs in order to clear general traffic. If you believe you may have been paused, reach out and we'll let you know.

monitoring
A fix has been implemented and we are monitoring the results.
May 18, 5:37 PM
identified
We have received reports of increased report latency for larger projects (5K file and up). We are doing our best to clear the background job queues for these projects. If you have one of these projects, feel free to reach out and we'll check status for you.

investigating
We are currently investigating an issue with an apparently expired SSL cert. Our orchestration layer shows no issue with certs so we need to dig deeper.
