TechCrunch noted this Fortnite outage and was able to replicate it. The game was continuously held for about five minutes and then timed out. Epic games reported a “minor service outage” that affected game services.

Within three hours of acknowledging, Epic games also issued a fix for the issue and let the users know on Twitter:

A member from Epic Games explained the reason for the Fortnite outage on Reddit: “Quick summary is that deploying a fix for elf challenge reward not being granted exposed a latent bug in our profile migration code (the code that fixes up players). This caused players to be kicked etc and triggered our waiting room. We fixed the issue and deployed a new backend, however, didn’t see a recovery in login success.

This ended up due to “sticky session” configuration having been lost on our waiting room load balances when moving them to ALBs. This meant that there was a 90% chance of having to requeue after hitting the front of the line. D’oh. This should all be fixed now and we are seeing a recovery in numbers/login throughout / waiting room / etc.”

Gamers have appreciated the company’s transparency in letting users know about what happened: “As a company, I applaud you for your transparency. It is highly unusual and I hope you continue to set precedence in this industry.”
