Update: Problem on my side. See Re^2: search.cpan.org broken?.


Hi!

Since about two or three weeks, I can't use search.cpan.org. I can ping it, but the web server lets any connection run into a timeout. Did I miss something?

The problem is not in my home network. I have the same problem from the network at work, using a different provider, different DSL box, different firewall.

Ping / traceroute / nmap output from home network:
