We have implemented a solution to this problem and, based on current observations, the service resumes normal operations. We will continue to monitor to ensure that the impact has been completely mitigated.July 22, 2021
As you may have noticed, Steam doesn't work: The Unofficial Steam status the site indicates that most services, including the warehouse and community, are not currently available.
The good news, as it stands, is that it’s not just about Steam. The cut is apparently the result of problems in Akamai DNS Edge Services, which currently suffers from an "emerging problem" that also affects other services. GamesRadar has reported that, for example, the PlayStation network has also crashed and that Epic also has issues, although right now it’s slow, but it seems to be accessible.
The Epic Games store / launcher is currently affected by a larger Internet issue affecting various online services. We will provide an update when players can use Store / Launcher normally.July 22, 2021
Right now, Valve has no say on the problem, but it’s actually out of Valve’s hands: seconds The Verge, other services, including banks, brokers and possibly even some 911 services, were also affected by the fall. Akamai said yes working on the topic and post periodic status updates.
We will take care of things and let you know when you return.
