Here's what I'm getting:

    Sorry, 175 pings gave errors or timeouts. 66 from 109 IPs were reachable. - no record will be made.
Seems like it's down again.

Working on it now. Thanks.

EDIT: It appears there may be some ICMP filtering in place someplace because I just checked with a verification tool on the site and all but two were up. I've removed them from the list, but Dr. Ping failed for me as well and I'm on a different network.

I'll try to figure it out. Please be patient as it might take some time.

I just tested on a Bellsouth connection and I was not given that error. What provider are you using and do you know if they are ICMP filter ?

My profile is set to show my provider (Cox HSI) in every post.

I'm not sure what you mean about them using ICMP filtering. Cox, like many ISPs, sets some of their routers to filter echo requests. If it helps, here's a tracert to one of the IPs appearing in a Dr. Ping report:

See above for your first post to this thread... Your ISP wasn't visible, probably because of some of my site preferences...

I'm not sure what you mean about them using ICMP filtering. Cox, like many ISPs, sets some of their routers to filter echo requests.
Somewhere along the way, ICMP packets are being dropped, either at the destination or along the path between you and the destination (which could be in Cox's network). The test I ran last night that failed was run from a Cox connection as well, just in a different area. With a Bellsouth connection, however, it worked fine.

And I do remember Cox had done some ICMP echo request filter and traceroute packet filter for awhile there...

If it helps, here's a tracert to one of the IPs appearing in a Dr. Ping report
Unfortunately, if you can see the address in the report, I'm fairly certain it was one of the addresses that wasn't causing a problem.

After running, Dr. Ping takes me to the output at this webpage.

I don't know if you can display this page. The page shows the following:

Sorry, 151 pings gave errors or timeouts. 75 from 107 IPs were reachable. - no record will be made.

???

Do you mean to say that in addition to Cox dropping ICMP echo requests directed to their own routers they are also filtering traffic to prevent echo requests being made to upstream IP addresses that they don't own? I've never heard of that, or seen any evidence of that.

Back with one of the worms, yes, they were doing that.

Yes, hosts that are failing are not showing up in your list...

I just ran the test and I had 107 hosts/routers listed in y results versus just 70-something in your list.

However, I might be able to compared lists and see what's happening later.

Right now I'm cleaning up a virus...
