Coveralls Outage History

Coveralls experienced increased report processing latency for large projects (5K+ files) due to background job queue backlogs, with a small number of high-volume repositories causing 75% of the traffic and creating delays for other users. The team resolved the issue by moving outlier repositories to dedicated processing queues and manually clearing backlogs, allowing normal processing times to resume for most projects. The incident was resolved after 10 days when the main background processing queue showed no backups for 48 hours.

Coveralls experienced an SSL certificate issue that affected both their web interface and API services. The incident was classified as minor and lasted 29 minutes while the team investigated the apparently expired certificate. The issue was successfully resolved after investigation revealed the root cause beyond their orchestration layer.

Coveralls experienced a 139-hour service outage affecting both their web platform and API due to an automated account restriction by their hosting provider that prevented access to their infrastructure. The outage disrupted CI workflows for users who depend on Coveralls for code coverage reporting, prompting the company to recommend using fail-on-error options to avoid further CI disruptions. Service was gradually restored after three days of working with the hosting provider's account team, with full resolution confirmed after additional monitoring across all regions.
