mod_accel can do primitive load balancing (via DNS) and primitive fault tolerance. It connect to next backend 1) if connect() to current backend failed; 2) if it can not get HTTP header from backend (timeout or error); 3) if it received 5XX response from backend (it can be disabled). Nevertheless it does not remember any faults to future use so I called it primitive. You can find it at http://sysoev.ru/en/ If you use DNS-based load balancing then you should install local caching DNS server on the same computer to speed up DNS queries.
