On Nov 13 our site had an incredibly deep crawl according to GWT - biggest in a very, very long time (100% higher than the average daily crawl). Which is kinda odd because my own internal stats that track Googlebot didn't detect it (so I'm wondering what exactly it was crawling!)
On Nov 14 we started losing traffic, about 15% from the day before (and our traffic should be increasing each day this time of year).
Mozcast shows the SERPS with a fever of 102 for Nov 14 so I assumed this must be another Google slap (Panda hit site) but then I noticed in GWT that googlebot encountered some DNS errors with the site on Nov 14.
There wasn't much chatter about an update happening on Nov 14 here in the forum so I'm trying to determine what happened. Would DNS errors encountered by Google cause a traffic drop? (and I have been working with my webhost to see if there are any DNS issues and we can't find a single thing wrong).
Did anyone else experience a drop in traffic (ie Panda update) on Nov 14? This site had been in a recovery from Panda up until this hit so I'm concerned we've backslid now for some reason.
