I will add a bit more context as to some of the ESI failures, as it’s, unfortunately, more widespread than this endpoint. he Market data endpoint has been down, and now two relating to character corporation history (though afaik not alliance history), are down or impaired.

The TL;DR for why these endpoints were taken offline is that there is a third-party developer, or a series of third-party devs, using AWS and requesting information from these endpoints so frequently that it puts the rest of the server at risk. These are on the scale of a 6,000% increase in hourly requests. Typically we’d use IP bans to stop the attack and then players would reach out to us, however, that strategy is no longer working in a climate where AWS can assign another IP immediately.

The team is aware of how severe these outages are and are actively pursuing solutions that will restore functionality and give us more tools to block errant programs or bad actors without taking the entire service offline.

Just a few days ago, ccp swift went into further detail what happened and why its not a quick fix
