Googlebot issues...

After recently installing vBSEO and uploading a site map I decided to check the google webmaster tools. One thing I found odd was google is listing a TON of pages as 404. Thing is, all the links are valid and I can visit them without a problem. Is that normal? Will it subside? Do I need to do something to resolve this issue?

did you have downtime? usually there's a timestamp next to it when it tried to view it

you know...come to think of it yes...

Why I didn't think of that, I do not know...haha

Well thanks for helping me figure out the obvious!

I moved my forum from forum.* to *.net/forum and in the process I had to take it down for a split second. Better preparation on my behalf could of avoided this issue but I'm learning as we go along, heh.

On a positive note...I'm already seeing positive results from vBSEO and the vBSEO Sitemap generator...nothing to get worked up about but some new stuff is already popping up on google.
