Random 429 status code for Mojang APIs

Hello,

As of day before yesterday sessionserver.mojang.com/session/minecraft/profile/id and api.mojang.com/users/profiles/minecraft/name return random 429 status code and weird string, even when it is a first request to that endpoints.

I think a similar problem occurs also for authserver.mojang.com, because sometimes is a problem to join online mode servers.

On the picture I show these error with curl verbose for api.mojang.com:

This error lasts from a few to tens of seconds.
