Time sure flies... it's been 3.5 years since
this topic, and now it's maybe that time again. The server that hosts these forums has become overloaded and very unstable lately, and the hosting company is on and off blaming it on these forums. I'm not that keen on upgrading to semi-dedicated hosting (at six times the cost) just to host a personal hobby forum though... but the server seems to have more problems than just my site as well, so it's not exactly certain that a more expensive hosting plan is really needed.
For now, both I and the hosting company is monitoring the server and this site to try to get to the bottom of the problem. In the mean time, you may continue to experience intermittent downtime of the forums, but please bear with it.
If it turns out that more powerful hosting is really needed after all, I'll have to reconsider how to proceed I guess, but I'll cross that bridge when I get to it.
