This morning, and again this evening, an automated bot attack temporarily overloaded our servers, preventing some users from accessing their exams. We’re relieved to report that the issue was quickly resolved, no data was lost, and everything is now running smoothly.
We’ve blocked a significant number of the bad actors, increased our capacity by 4x, added a more aggressive auto-scaling configuration, and implemented additional alerting so we can manually look ASAP if it happens again.
We understand how important it is to be able to prepare for your exams when needed. We sincerely apologize for any inconvenience this may have caused, and appreciate your patience.
Thank you,
Justin
