Three are active
ATM, in fact.
The forum posts are repllicated across both servers and normally you cannot tell which one you are looking at.
However, when you add an avatar, it is only loaded to the .net server and will gradually permeate across to the other server.
Very close.
The servers all share the same database, and hence the messages all appear on all sites with no issues.
The codebases, while identical, are stored locally on each server.
The avatars too are stored on locally on each server, and that's where the issues arise: if yo're logged on to dslrusers.net, that's where your avatar is stored. If you then go and look at dslrusers.com, the avatar, which is stored locally on the .net sewrver, doesn't (yet) exist on the .com server, and thus it cannot be displayed.
We have routines that run periodically to synch the three servers together, and they take care of ensuring that the three avatar directories match from time to time.
Why three servers is the next question of course.
We started out as D70users.com, then mocved servers. In order to minimise disruption, we acquired D70users.net and then pointed everything there once we updated the new site with the data.
Then we saw that we were attracting a wider base of users. At the same time we dedcided that the D70 wasn't going to be around for ever, so we acquired DSLRusers.com.
Then we had a minor issue with our hosting service, which didn;t like too much memory utilisation of their shared servers. HEaps of bandwidth, heaps of storage, just don't ever try to use it.
They measured that by server, and so, by simply using different servers within their system we could spread the load and still keep the site active and running.
Hence three sites.
