Xbox Live has come down with a nasty case of the gremlins, as users report difficulties signing into the service via both Xbox 360 consoles and their desktops.
"We are aware of the problem and are working to resolve the issue," reads a note on the Xbox Support status page. "We apologize for any inconvenience this may cause and thank you for your patience."
Bit of an unfortunate turn of events, isn't it, given the moments-ago release of a new Skyrim DLC pack? We'll go ask Uncle Microsoft what's up. While you wait, consider this enormous list of the best upcoming Xbox Live Arcade games.
Update: Just had a statement through from Microsoft PR.
"We're aware that some users may be experiencing difficulty logging in to Xbox LIVE at present. This does happen from time to time while updates and fixes are made to the system and should not be symptomatic of any larger problems.
"A service update can be found on Xbox.com, alerting Xbox LIVE users to the current state of the service. I don't have an update on timeframe for service to resume as usual, but we are working on the problem."
Update numero duo: There's a rumour doing the rounds that Xbox Live has been hacked. It's based on the say-so of a lone Gamespot forumite, apparently, and smells strongly like an absolute load of cobblers.
Update numero tres: It seems to be coming back up now - Avatars aren't showing up properly, but we're able to connect to the service and download from Marketplace.
Update numero, er, quatro?: You can sign in but individual services are turning off and on again like that bit when Nedry tries to steal the embyros in Jurassic Park. Hopefully with less dramatic consequences.
Final update: It all seems to be working fine now. Which is handy, because we don't know the Spanish for "five".
