## Updates from Ably
### 2026-10-01 15:36 UTC: investigating
We're experiencing an elevated level of API errors and are currently looking into the issue.

### 2026-10-01 16:03 UTC: resolved
Between 15:30 UTC to 15:36 UTC there were elevated errors affecting token requests in all regions resulting in 503 error responses.

### 2026-10-01 17:20 UTC: postmortem
On October 1, a distributed denial-of-service \\(DDoS\\) attack caused elevated token-request errors across all Ably Realtime regions for approximately six minutes and intermittent unavailability of ably.com (http://ably.com). We restored token-request service by increasing capacity and added targeted traffic-blocking and rate-limiting rules to mitigate the attack. We are strengthening endpoint protection and reviewing our firewall controls to reduce the risk of recurrence.
