After 10 hours of downtime, PSN now back up and running [Update]

Ten hours later, PlayStation is go.

Update 2: The PlayStation Network is now up and running with all services green for go.

Update: Sony has acknowledged the outage and the status page now shows all services being offline with the message, "Our engineers are working to resolve the issue as soon as possible, and we thank you for your patience."

Original story:

A number of reports from around the world are suggesting that PSN is offline.

The PlayStation Network is having some issues, and is inaccessible to many users. The number of reports on Reddit and Twitter from affected users keeps increasing, pointing towards a worldwide issue rather than a regional one.

Upon attempting to login, users get a message telling them the network is undergoing maintenance. Sony has not announced a maintenance window prior, and the official status page hasn't been updated to reflect the outage.

Matt and myself have just checked, and we too received the same message.

We'll keep you updated.
