Thanks. It seems to have settled down now the DNS has been refreshed.
I’ve also cut the number of posts on the front page down a bit.
Thank you very much.
I’ve refreshed the DNS to see if that helps. If it doesn’t I’ll get in touch with Dreamhost.
I’ll take a look at cloudflare, but I’d prefer to try and find a solution to the slowdown rather than using another service to patch over it.
