The Windows Phone 7 Series website is currently titsup less than a day since Microsoft launched its iPhone-competing gadget.
We asked the company what had gone wrong, but at time of writing Microsoft hadn't got back to us with comment.
The website has one simple message that reads "Service Unavailable".
Microsoft baptised its smartphone yesterday, giving it the clunky name of Windows Phone 7 Series - which seems to be Redmond's attempt at distinguishing its gizmo from the Apple iPhone and Google Nexus crowd by giving it a car-like moniker.
Earlier this morning Paul Wright, who describes himself as a 'Windows Mobile Marketing Maverick', blamed heavy traffic to the site for its current, unscheduled lie-down.
"Due to the unexpected number of click-thru's to the Windows phone 7 Series website it's decided to crash, will have it back up asap," he said on his Twitter account about two hours ago. ®
