I have had some bad experiences with ISPs that provide redundant connections for routable IPs. Apparently, there can be some serious issues with rerouting IPs through a secondary connection if you are configured for OSPF.
I prefer to use physically independent locations that are at least 100Mi apart. This way, if a region experiences a catastrophe, you are probably still online at the secondary location. It makes management a bit more painful, but well worth the extra effort!

Have a look at: http://www.ietf.org/rfc/rfc2168.txt http://www.ietf.org/rfc/rfc2782.txt Microsoft uses it in their Active Directory service in Windows 2000/2003, but I don't know of any webbrowsers that support this yet. Some more useful ideas: - Set the TTL for your DNS-records to something extremely low and update them as soon as your primary connection goes down. For example, DynDNS.org uses a 60-second TTL. - For e-mail, you can set up a second MX-record pointing to your second internet connection - Find an ISP that can provide you with a backup connection that allows you to use the same IP range as the primary connection Maarten ------------------------------------------------------ To unsubscribe: [EMAIL PROTECTED] For additional commands: [EMAIL PROTECTED] Archive: http://archives.gnatbox.com/gb-users/ ------------------------------------------------------ To unsubscribe: [EMAIL PROTECTED] For additional commands: [EMAIL PROTECTED] Archive: http://archives.gnatbox.com/gb-users/
