Massive surge in HTTP 403 forbidden errors

This started happening today, lots of people are having issues teleporting as well as seeing their friends statuses/locations in game (using GetPlayerPlaceInstanceAsync).

This has never happened before for our game.
I’m not sure if I should mark this as critical or not, other games seem to be fine (?)
The game this is happening in is Adventure Up!

This is probably related to Internal HTTP (authentication?) failures (InsertService, MarketplaceService, etc)
