I concur with this. Take your business critical hosting needs and put them into a co-location environment where everything is redundant. You can handle getting your web access and email access fully redundant over your links, but the inbound is ugly unless you have the money to spend on BGP-routing and redundant T's.

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/ __________ NOD32 1.986 (20050127) Information __________ This message was checked by NOD32 antivirus system. http://www.nod32.com ------------------------------------------------------ To unsubscribe: [EMAIL PROTECTED] For additional commands: [EMAIL PROTECTED] Archive: http://archives.gnatbox.com/gb-users/
