Wikimedia thumbnail urls all giving 429 errors

[frnsys]

Hello, thanks for the Openverse API. I'm having a small problem where no matter what I try all the wikimedia thumbnail urls give me a 429 Too Many Requests error. This started from even my first request.

For example, for the thumbnail https://api.openverse.org/v1/images/89fc9c11-0710-4bcd-bde1-5e4fb6612dc8/thumb/

The error page shows:

HTTP 424 Failed Dependency
Allow: GET, HEAD, OPTIONS
Content-Type: application/json
Vary: Accept
X-RateLimit-Available-anon_thumbnail: 999
X-RateLimit-Limit-anon_thumbnail: 1000/day

{
    "detail": "Failed to render thumbnail. 429, message='Too Many Requests', url='https://i0.wp.com/upload.wikimedia.org/wikipedia/commons/thumb/b/b1/The_Hermitage,_Cat_Island,_Bahamas.jpg/lossy-600px-The_Hermitage,_Cat_Island,_Bahamas.jpg.png?ssl=true'"
}

which seems to indicate I'm well below the rate limit. I'm not using a VPN or anything like that either.

Trying the url directly: https://upload.wikimedia.org/wikipedia/commons/thumb/b/b1/The_Hermitage,_Cat_Island,_Bahamas.jpg/lossy-600px-The_Hermitage,_Cat_Island,_Bahamas.jpg.png, for example, shows a Wikimedia error page with:

Use thumbnail steps listed on https://w.wiki/GHai. Please contact noc@wikimedia.org for further information (92dd0a1)

Is there anything I can do to resolve this, or is this a temporary problem with the service? Thanks.

Edit: for the same url I'm now getting Thumbnail unavailable from provider.

After some sleuthing, maybe Wikimedia changed its default thumbnail sizes? The redirect in my example goes to a 600px image which as I mentioned shows that "Use thumbnail steps..." page. Changing "600px" to "500px" (to https://upload.wikimedia.org/wikipedia/commons/thumb/b/b1/The_Hermitage,_Cat_Island,_Bahamas.jpg/lossy-500px-The_Hermitage,_Cat_Island,_Bahamas.jpg.png), which is a size listed on that instruction page, causes the thumbnail to work. So I suppose the generated thumbnail URL needs to be updated?
