Anthem is going live today for EA/Origin Access members, but it appears that launch is not without its issues. According to players, servers have hit capacity and many are stuck on the start screen and informed that "services are currently unavailable". EA Help tweeted that it is aware of the issue and is working to address it ASAP.
Hello, Freelancers! We understand some of you are having issues connecting to #AnthemGame servers right now and we’re working to address it as fast as we can. Please hang with us and try again in a few minutes.— EA Help (@EAHelp) February 15, 2019
This appears to be the same issue that plagued the Anthem demo experiences, both during the Closed Demo and the Open Demo last week.
