Systems remain stable, and we are continuing to monitor the situation. Bi-directional sync was on a maintenance job from 9:50 - 11:59 AM (ET) and is now operational.
Systems remain stable and our team continues to deploy targeted fixes. Work is ongoing to address degraded read performance across the system, including serving all 404s from cache. We’ll be actively monitoring over the weekend, and we will provide a full RCA next week.
Our systems have been stable since Friday, May 29th. We're monitoring closely and improving spike detection to prevent recurrence and adding proactive capacity monitoring to detect admin dashboard degradation before it impacts customers. Full root cause analysis coming soon. Thanks for your patience and understanding.

### What Happened Beginning Tuesday, May 26, 2026, customers were experiencing slow loading and 503 errors across ReadMe-hosted docs and the admin dashboard. The outage was intermittent but recurring, with the worst periods hitting during business hours when traffic spiked. ### Root Cause An internal data backup process was generating excessive I/O on our storage layer. Under normal traffic conditions, this additional load was manageable. But when it coincided with peak customer traffic and elevated bot activity, total I/O demand exceeded system capacity, causing cascading request timeouts. The maintenance process ran on a recurring schedule, which is why the degradation followed a predictable pattern of spikes throughout each day. Separately, a surge in bot traffic to non-existent pages \(404s\) amplified the problem because those requests were not being served from cache. ### Resolution **Immediate fix:** We identified and disabled the maintenance process causing the excess I/O load. Within three hours, storage utilization returned to normal levels and remained stable. **Additional improvements shipped during the incident:** * Expanded caching across multiple layers, significantly reducing load on backend storage * Hardened 404 handling to serve error pages from cache instead of hitting the backend * Implemented rate limiting and IP-based protections against abusive bot traffic * Optimized several high-traffic API endpoints to reduce redundant backend calls * Added new monitoring and alerting for storage I/O thresholds ### Timeline May 26 - June 1, 2026 | Time | Status | Details | | --- | --- | --- | | Mon 5/26, 6:39 AM PDT | Investigating | Issue reported | | Mon 5/26, 7:26 AM PDT | Monitoring | Fix implemented, monitoring results | | Mon 5/26, 8:37 AM PDT | Resolved | Admin hub incident resolved | | Mon 5/26, 10:41 AM PDT | Investigating | Slow performance across customer hubs | | Mon 5/26, 10:49 AM PDT | Monitoring | Quick fix applied, investigating thorough fix | | Mon 5/26, 8:54 PM PDT | Resolved | Customer hub incident resolved | | Tue 5/27, 6:51 AM PDT | Investigating | Issue reported | | Tue 5/27, 7:52 AM PDT | Identified | Fix in progress | | Tue 5/27, 8:57 AM PDT | Monitoring | Slowly recovering | | Tue 5/27, 10:17 AM PDT | Update | Updated 6/3: A routine configuration update coincided with the downtime window, which led us to initially identify it as the cause.

Systems stable since Thursday, May 29. | ### Path Forward We are using this incident to make lasting improvements to reliability and incident response: * **Storage capacity and isolation:** Restructuring how background processes interact with production storage to eliminate contention under load. * **Caching and performance:** The caching improvements shipped during the incident are permanent. We are continuing to expand cache coverage across additional endpoints and page types. * **Bot and traffic protection:** Strengthening rate limiting and abuse detection to prevent bot traffic from contributing to backend load. * **Monitoring and alerting:** Adding proactive capacity monitoring with earlier thresholds so the team can intervene before customers are affected. * **Incident response:** Improving our internal processes for faster escalation and more frequent status page updates during multi-day incidents. ### Final Note During the incident, we posted an update referencing a platform update. That was our initial hypothesis based on timing. Further investigation confirmed it was unrelated. The change in question was a routine, isolated configuration update and had no impact on the outage or any other customers. We should have waited for confirmation before publishing it, and we're tightening our internal process for status page updates as a result. We know how critical your documentation is to your customers, and this level of disruption is not acceptable. We have already shipped meaningful improvements to prevent recurrence, and the work outlined above will continue through the coming weeks.
