The HTTP 429 Too Many Requests response status code indicates the user has sent too many requests in a given amount of time ("rate limiting").
Unless the server believes you as an individual user were sending too many it should not have been a 429
If the server was unable to handle the volume of requests more generally it should have been a 503 which also supports Retry-After
