My site was being visited by google daily and new posts would be indexed generally within 48 hrs of being posted (its a Wordpress blog with 2-4 posts being added daily). This all stopped on the 13th when googlebot made its last visit.
Googlebot has not been seen since, the indexed pages have remained unchanged for the last 5 days and traffic doesn't seem overly affected.
Has anyone else seen this odd behaviour or know anything about it?
Yes, I am hoping that is all it is, or maybe something to do with the stalled pagerank export but in three months I havent seen this happen with my site, Googlebot has been by everyday without fail until the 13th.
If you really suspect something is wrong, you might want to make sure Google isn't blocked on your site by IP (you might try to ping or traceroute back to the site/IP where the last/most recent Google access came from)
