I attempted to mass-block few ranges via the gadget stewards have available to them, and it didn't do anything. I investigated, and I noticed this API call:
{ "action": "globalblock", "format": "json", "target": "213.202.232.64", "expiry": "1 minute", "reason": "Testing", "modify": 1, "token": "redacted" }
consistently fails in Wikimedia production. So far, I'm unable to reproduce with beta or dev setup.
Response from production:
{ "error": { "globalblock": [ { "code": "globalblocking-block-failure", "message": "An error occurred while attempting to globally block 213.202.232.64. Please try again." } ] } }
Submitting the very same request, but with 127.0.0.5 works fine.
