Let me know if things are still weird in a few days. The oceantiles.dat on the server is updated once a day but it will only be using the new one when apache processes reload themselves.

I think there could be a nice way to split the load between two or
more servers, at least for serving tiles without much overhead. Does
someone already work on it or should I'll try to do it?
Anyway the idea is to make a small publish-subscribe API, so when a
server gets new tiles from a client it sends a message to all
subscribers with the appropriate coordinates and layers, which they
download from the master server. To ease up bootstraping, they could
issue a HTTP 307 or 300 code in case a requested tile isn't on it and
download it in the background so no further redirects will be needed.
Heck, this could even open up the way for region based servers...
