I’ve confirmed that there’s some kind of problem on the Internet, that only seems to affect users of the Internet Explorer 7 web browser. Attempting to browse to many sites results in an ‘Operation Aborted’ error. No information about the problem elsewhere yet ... stay tuned.

It appears to be related to Sitemeter.com — browsing to their web site with Internet Explorer 7 produces the error too.

Site Meter now reports all systems go.
