I could try doing a tracert (or the like) from here if it would help.

I can see the nameservers for that base according to http://host.robtex.c....net.html#records (i.e. ns1.level3.net and ns2.level3.net). Nothing seems amiss getting to the nameservers.

There are lots of historical complaints about 100% packet loss with the server base you mentioned, but nothing is showing up for me since 2012.

HTH a tiny bit. Good luck.

Cheers,
Scott.
