PlayStation has confirmed the issue after a good number of people complained of the denial of login. Further interruptions are appearing as more players express their dissatisfaction on Reddit and Twitter.
After we saw the countless of complaints, we went to PlayStation’s official Network Service Status page, where it shows that many services are currently unavailable. It appears that many do not know the cause for this reason, but the frustration is visible.
What we know so far is that PlayStation has officially confirmed that they’re working on the issue, for which we’re waiting for another answer.
We're aware that some users are experiencing issues logging into PSN. Thanks for your patience as we investigate: https://t.co/NJX2xGusZM

Sadly, players are still not able to log in, for which might be quite a disturbance before a weekend when all the gamers are awakened. Hopefully, Sony will figure this out as fast as possible.
