Hello David, Sunday, August 06, 2000, 11:51:42 AM, you wrote: > The traffic coming out of the web servers (or whatever) goes through > "front end servers", and there too you can put as much as you need. Outgoing traffic won't be a problem in any case as the backend servers could be configured to use another router. But what's going to happen if the primary frontend server for imconing connections fails? We've recently had a box in a state where it did respond to pings but no daemons were responding for about two hours... I for my self can see no way to protect you from such a scenario without some hardware failover technologies. I relying on DNS for failover tasks is a pretty bad idea (you can't say how the foreign DNS servers are caching your records even if you set their TTL to 10s or so...).
