Can ONE single user encounter download difficulties with ONE site only?
Our site (www.vendelcommunications.com) is hosted by Yahoo. Previously, we had no problems to download/view the site ourselves. About a week ago, it became virtually impossible. All of a sudden, it took forever, or stalled completely.We're having no problems what so ever with any other site.
At the same time, our e-mail accounts with Yahoo (POP and SMTP) became unstable. We've set our client side e-mail apps to connect to the server every 3 minutes, and about every 10 times, the app can not connect at all. This never happened before.
First, I approached Yahoo and told them something was wrong with their stuff. They claimed not.
Then, I mailed our ISP. They said they couldn't find anything wrong in their equipment.
Then, I pinged and traced the site. The pings didn't come back. The trace showed that it stalled near Yahoo somewhere (unknown.Level3.net 209.245.56.18).
I have had friends with other ISP

Questions: Is it possible that ONLY WE can have problems with ONE SITE (ours) only? How often will a route stay the same (I thought it changed about every time I connected to a site)?
Can someone enlighten this ingoramus?
Thanks
