Argh
I switched the web server to the standard port 80 last night.
Sometime this morning RoadRunner decided to start blocking port 80 requests.
I switched the web server back to a non-standard port - all is well now.
Why use a non-standard port? Why would RoadRunner block port 80 requests?
One word...CodeRed...July 2001...

Another word...Apache
...not Microsoft IIS
The real question is: Why did they wait until mid-morning to start blocking requests?
