Now getting this myself using XP Home & IE7 - was OK earlier today. Refreshing page does not cure it. Anybody else getting the same?
Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /amserver/SSORedirect/metaAlias/sky.
Reason: Error reading from remote server
--------------------------------------------------------------------------------
IBM_HTTP_Server Server at id.sky.com Port 80
Edit continual refreshing eventually states
Most likely causes:
The website is under maintenance.
The website has a programming error.
No real surprise there then!
