We’re currently experiencing some extended issues with .NET2 on our shared win1 server as a result of this mornings maintenance. Further information will be posted shortly.
UPDATE: 10:24am – We have performed a workaround, please retest all your sites.
UPDATE: 10:30am – We’re currently aware that some special sites with .NET1.1 are still experiencing issues. These are being dealt with now.
UPDATE: 12:00am – All medium trust .NET1.1 sites should be working correctly now.
