The mailing list for listmasters using Sympa

[Dan Pritts <address@concealed>]

We're looking to improve the availability of our Sympa system here at Duke, to hopefully prevent the risk of having a single point of failure as we do now, with one machine on one network in one data center running the service.  It looks like running a hot/cold failover system would be simple enough, with a load balancer routing mail appropriately and each system being aware of all the lists.  I don't know how well archives would work with such a setup, though, unless we were doing some sort of shared storage (e.g. NFS), which introduces its own set of problems.

checking through old mail ...

Archives are just static HTML so i would suggest you just periodically rsync them from one server to the other.
