I deleted your question, for these reasons:
It's not really on topic.
is not about:
- consumer workstations or networking (which belong on our sister site, Super User)
The tour also mentions this.
Don't ask about...
- Anything in a home or development environment
It was reposted from another site, while still being open on the other site. Generally, questions should not be reposted on a site while they are still active on another.
Where do you ask? I'd send the question to SU, but you've already posted it there.
Ultimately, none of the sites will get you an answer that resolves your connectivity problem. Either SF or Network Engineering could probably explain the problem in a depth you might not understand, but probably could not tell you exactly whose fault it is. And there's probably already a Q&A on SF somewhere that does so; I haven't gone looking for it yet. SU could also explain it, probably more clearly for an end user, but still couldn't help you actually connect to the web site.
