Outage in Coveralls

Increased latency for large repos

Resolved Minor
July 15, 2026 - Started 9 days ago - Lasted 5 days
Official incident page

Incident Report

Summary AI Generated

Coveralls experienced increased latency affecting large repositories (those with 5,000+ source files), impacting both the web and API for approximately five days. The root cause was excess requests in large repo queues, which were proactively throttled, reducing queue traffic by 75%, though latency remained elevated by around 30% during the monitoring period. The issue was fully resolved over the weekend of July 19–20, 2026, with a longer-term fix implemented and queues continuing to be monitored.

All systems fully functional. We have identified increased latency for large repos again and have proactively arrested sources of excess requests. We expect to restore normal latency within the hour.

Latency remains elevated by about 30% for large repos. We are continuing to monitor and do what we can to mitigate until we can implement a longer-term solution.

MONITORING 8 days ago - at 07/16/2026 06:25PM

We are continuing to proactively monitor and clear the large repo queues.

We are working on a longer term solution over the weekend and will post about it in the postmortem for this issue when complete.

We will keep this incident open as long as we have large repo queues with above-average latency.

MONITORING 9 days ago - at 07/16/2026 12:47AM

We are continuing to monitor for any further issues.

MONITORING 9 days ago - at 07/15/2026 06:14PM

We have reduced traffic in affected queues by 75%. We still expect to clear the queue within about 1 hr. We will post updates here. If you think you may have been paused as a user with a large repo (>=5K source files) that has uploaded 3-10x normal daily uploads, please reach out to us at support@coveralls.io and we'll confirm and give you some next steps to avoid further pauses (see Usage Add-Ons at https://coveralls.io/pricing).
