If you’re looking for the service status of Windows Live Messenger (aka MSN Messenger), go to the Microsoft Service Status page.
I think MSN is having problems again, since I’ve had 18 new comments posted to the MSN Typo article in the past 3 hours, all from people who cannot connect to the MSN Messenger service. No word from Microsoft about the problem though.
I’m connected to the network okay via Trillian but I have a feeling that it is affected too since the status window didn’t show the contacts being retrieved at signon, however Trillian stores the contact list locally so the only effect of this is that fewer people appear to be online. It also looks like some accounts are affected and others are not.
