I cannot connect to gnutellahosts.com or router.limewire.com past 2 days using BearShare or Gnutella. They've worked fine for past 6 months.

What's going on? Has Optimum Online (cablemodem ISP) blocked their traffic?

i can ping these sites. Maybe they're blocking port 6346 connections?

I'm located in Connecticut.

any tricks I can use to test if they are blocking the traffic?
i.e. netstat?
