Apparently it slows after heavy demand from Google as it ‘Spiders’ the site. This means that it is indexing all of the content on here for reference in its searches (ultimately a good thing for the site). Should be finished soon but Google looks at every page and every link from that page so it can take a couple of weeks. Other sites are reporting similar speed losses, so please bear with it for a while. Just looked this morning and it had 32 ‘bots’ crawling the site at the same time!
