Cannot access a specific webserver


We're having a bit of a weird problem here. It turns out we cannot access two specific websites "" and "". The just forwards the request to the address, but both have different ip address: = =

The weird thing is that our DNS server can resolve these addresses just fine, but for some reason we are not able to access them. We also tried to ping these addresses from the clients, as well as the router and it's seems it's somewhat intermittent (see the screenshot).

Any suggestions?

Clear your DNS cache.

Add updated DNS Forwarders

We already tried that, without success. We even added some opendns forwarders but that didn't help either.

Really points to a network issue.

Run dcdiag post results

We renewed are public IP-address and it seems to work again. Thanks for your help, though.
