my websites daneel.net et plcoder.net are hosted on a french hosting services provider, and are unreachable from a canadian server since august 1st 22h35 GMT+1.

Ping work well, and IP is good.

(~)$ ping www.daneel.net
PING pessac.nexen.net (217.174.203.6):
56 data bytes 64 bytes from
217.174.203.6: icmp_seq=0 ttl=48 time=97.602 ms

SSH work well

(~)$ telnet

and FTP too, but not HTTP

(~)$ wget daneel.net

Retrying.

From my canadian server others french web sites are reachable, even in the network of my french provider.

How can I understand where is the problem? One the french server or on the canadian one? On the french one I only have ftp and http access, one the canadian I have a ssh shell. It is not the first time my websites are unreachables from the canadian server, but it had run for months without problem.

thanks for your help

If you have root access you could try the tcp traceroute option if available e.g. under linux it would be:

traceroute -M tcp -p 80 www.somedomain.com

That will try to connect via port 80 over tcp. Hopefully you will be able to identify where the problem is then.

Well, ask to the providers is the good answer, and one of them admit to have blocked the other's IP.
