## Timeline of updates

- **identified** 2026-09-02 14:18 UTC: We have observed an upstream network issue in LAX. Connections to some destinations may see elevated latency and packet loss. We're working with our upstream to resolve this issue.
- **identified** 2026-09-02 14:48 UTC: We have put in some temporary mitigations along with our providers. However since the root cause of this issue lies within a bigger upstream transit provider, you may continue to see some elevated latency and connection issues in/around affected regions. We're still working closely with them to resolve the root cause.
- **identified** 2026-09-02 14:56 UTC: We're updating the affected region list to also include SJC since this seems to be a wider upstream issue in US West Coast.
- **monitoring** 2026-09-02 15:33 UTC: A fix has been implemented and we are monitoring the results.
- **resolved** 2026-09-02 15:57 UTC: This incident has been resolved.
