Since yesterday (2026-01-07), Wiki Education Dashboard (dashboard.wikiedu.org) has started seeing 429 errors during the OAuth login flow and when fetching tokens to make edits on behalf of OAuth users.
Here's an example server response from trying to initiate OAuth login:
Request served via cp4044 cp4044, Varnish XID 735497657<br>Upstream caches: cp4044 int<br>Error: 429, Too many requests (f061ab2) at Thu, 08 Jan 2026 17:11:08 GMT<br><details><summary>Sensitive client information</summary>IP address: 2600:[ip]</details>
We aren't sending significantly different traffic patterns for OAuth than we have in the past, so I assume something related to the rate-limiting configuration has changed.
Our IPs for this are:
- 45.79.106.114
- 2600:3c01::f03c:93ff:fe24:db1b
