For the second time this year, Sony's PlayStation Network was down Wednesday until PSN service was returned, eradicating log in error messages experienced by users.

We're aware that some of you are having issues trying to log into PSN. We're working to resolve the issue, and we'll update you here, PlayStation tweeted Wednesday afternoon.

According to users in Europe and North America, an error message reading, An error has occurred. You have been signed out of PlayStation Network. (8002A548) came up when prompted for credentials at log in Wednesday morning.

Both the American and European PlayStation Twitter accounts declared service was restored around 6 p.m. Wednesday evening and users will be able to log in successfully.

The PSN restoration is now complete and you should all be able to sign in. Again, sincere apologies for the inconvenience, PlayStation EU tweeted.

According to rumors, the PSN was down due to routine upgrades though PlayStation has not officially made a comment.

The PSN was previously down for five days earlier this year following reports the network was the subject of cyberattacks.

According to CNET, the personal information of millions of PSN users was released during the hack, including credit card numbers.

Sony fired back issuing a public apology and promises to strengthen the PlayStation Network in addition to a $1 million identity theft police, free games and free access to PlayStation Plus to all members for a month.
