It looks like you are getting to an OpenDNS server instead of a
This looks like exactly the kind of stuff that OpenDNS does... They
redirect inexistant domains to their own servers. I think there are
also some options that you can request to redirect other domains (like
maybe ones used by ads?) to their servers.
To diagnose the problem I suggest you use "nslookup" on the two
machines to find out to which IP they are resolving
analytics.linksynergy.com, I think they will probably not resolve to
the same IP (if they do, then try to close and reopen Firefox, clear
the cache, and try the website again, maybe it was a temporary problem
and is now fixed). If the IPs are indeed different, then you can use
"whois" to find out who owns the IP, I bet the one that gives you the
certificate error you reported is going to be owned by OpenDNS.
If you need help using the tools (nslookup and whois) please reply to
the list and we'll happy to help you there. If you can resolve the IPs
with nslookup you can post them to the list as well.
