If the power and the fibre to the building has not been cut then our staff
can work from home, the library, or any Starbuck's hot-spot. Anywhere
that an Internet connection is available is a potential workspace. That
includes fax, email, access to the HP3000, etc. All over SSH/SSL/TSL.
Incoming telephone service would be routed through our 24/7 answering
service so that calls would still be answered at the usual number. The
only things not "easily" reachable are user files located on the
MS-Windows network. But even those could be had for a little effort on my
If power and connectivity to our primary site is cut off then it would
take less than four hours to completely switch over most services to the
secondary site located about 50 km away. Fax, email and HP3000 services
would be maintained although he alternate fax number would have to be
promulgated. Presently, static web services are replicated on the
secondary site every 24 hours while E-mail and fax traffic are replicated
on the secondary site every 20 minutes. Data on the secondary HP3000
would be, in the worse case, 24 hours out of date. A severe
inconvenience, but not an unmanageable one.
All done in-house via ssh, cron, rsync and (for the HP3000) ftp.
