Post-Mortem
Summary:
On Feb 10, 2026, a DNS resolution issue impacted the delivery of static assets for Sizebay applications in specific regions. The issue was caused by an external upstream DNS resolution instability and resolved automatically as DNS propagation normalized.
What happened:
Some users experienced intermittent access issues due to DNS resolution failures affecting specific resolvers and regions.
Detection and response:
The issue was detected immediately and investigated by the engineering team. All internal systems and delivery configurations were validated and found to be operating normally.
External signals:
During the incident window, independent reports from other services and providers indicated similar DNS resolution behavior, supporting the conclusion that the issue originated outside of Sizebay’s infrastructure.
Resolution:
DNS resolution stabilized automatically across affected regions without requiring internal changes.
Prevention and follow-up:
We are enhancing DNS resolution monitoring to improve early detection of similar issues in the future.
