Re: [cobalt-developers] Can the RaQ boot from floppy or CD?

[chris <chris@xxxxxxxxxxx>]

Hello Norbert!
you might be interested in contacting our office in France
(support@xxxxxxxxxx) as we offer Continuous Web Tone system: you
server would be duplicated in one of our networks, your database
would be continuously replicated on the mirror(s) and restored
from the mirror(s) in case of problem, your security updates
would be automatically setup on the mirror(s) machine(s).
An intermediate system would direct the http querries on one box
or the other(s) box(es) according to their availability; this
means that if a server is highly loaded, down, or if a full
network is down, then the mirror(s) will get the requests. This
is absolutely transparent for the visitor.

Should you be interested, please contact support@xxxxxxxxxx

sincerely,
chris
