Delayed replies to a single internal endpoint triggered a latent retry bug in VS Code that amplified traffic by approximately 10x and caused delayed recovery for the Copilot Token Service.
To be clear, that was during recovery, not a root cause.
The closest to that is this:
Neither outage was caused by a code or configuration change. Both incidents were capacity failures at their core. We failed to scale critical components before demand exceeded their capacity. Since April, monthly commits have grown from 1.4 billion to 2.9 billion. That growth explains the pressure on our systems, but it does not excuse these outages.
One could argue they still DDOSd themselves by promoting tools that produce commits at a much higher rate.
Exactly. Imagine the board meeting where somebody has to suggest “maybe we don’t want that many more users.”
I was about to type “customers,” but realistically a significant portion of this new load is on free plans.
So you DDOS’d yourself. Nice job.

DDOS by marketing
