We believe this incident is caused by an unknown network issue that is affecting a small amount of users. We do not have enough information to find the root cause of this issue. Our current recommendation is to try a VPN to get a different network route.
- investigating Sep 18, 2026, 05:36 AM UTC
Given this issue is only affecting a very small subset of users, this does not classify as a widespread service outage, and the recommendation stays to use a VPN and see if that works. Thank you for your patience. We will continue to investigate and provide updates as needed.
