RE: Interesting Assertions on W2K Stability

Agreed, with at least 2 servers located in two cities using two ISPs you can
get rid of any single point of failure.  Your server may still go down but
your site will remain up.  Again that is keeping your site up 24x7 not your
server.  The server will be down for maintenance, upgrades or what ever
other reasons but hopefully not both server at the same time.  This is why
we maintain a hot backup site in another location.  We can move our traffic
from California to Wisconsin and our customers will never know.  We switch
traffic and update one server, then test.  If testing works on the live
server, we switch traffic back.  The next day we will update the other
server.  And we still have down time due to DNS or Registry problems.

Our main weakness has been only one ISP.  We are switching this month but
not able to have two ISPs concurrently load balancing our traffic between
our two sites.  Maybe some day.

Why not? If it is truly that important, say a life support system. Wouldn't
you want it to be 99.9999% uptime or better?

2 redundant servers? Easy.
2 internet connections from 2 ISPs? Expensive but can be done. My previous
ISP did that. They were having problems with a ISPs uptime, so they got
another connection from a different provider as redundancy.
