Please excuse this off-topic question (and feel free to recommend any better
suited lists).
My firm has a single ISP (PSINET) and reliability has been reasonable over
the years using their T1 service. But we have periods where customers can't
ping us, or their tracerts show severe latency problems -- perhaps once a
week. Often we "lose" an entire geographic segment for several hours.
So I'm looking at adding a distinct, redundant ISP. But I'm uncertain how
this works.
All my remote clients will be pointing to www.xyz.com. That will resolve to
a single IP address, correct? But then how can one use multiple ISP's? I
know this can be done, I just would like to understand how. An suppose one
ISP's route is blocked, how does the client know to switch over to the other
route?
Also, any suggestions on the hardware needed to pull this off on the "my"
side would be appreciated. I've seen stuff like www.FatPipeInc.com which
seems to address this issue.
TIA
Harry
