You will have noticed recently that the site has become slow to load or is unavailable (FTTP500). When this occurred back in January the problem was due to a couple of other websites, hosted on the same server, which caused the server to slow down or stop. The hosting company has informed me that this time it is down to 15² using too much cpu time (something which I would question) so it is being throttled.
I am in the process of investigating ways of reducing cpu usage to see if this will improve the situation, such as limiting RSS feeds to summaries rather than full posts and reducing the number of posts shown on the home page. I still think that the problem is external to 15² but I cannot pursue this further until I have made some internal changes.
Please let me know if you have problems accessing the site or if the changes I make are a retrograde step.
