Spider Activity Seems to have died after server move

I'm not sure if its something I did or if I didn't correctly move our vbseo installation, but our # of visitors has dropped from an average of 1200 to about 400.

We moved servers, and duplicated our directories. The installation seems to work, as the URL's are coming up normally.

Any suggestions?

check write and chown permissions on the write directories.

otherwise, how long were you down for? if you took a long time to move and were offline for a bit, you might have been moved to sumplimental because google couldn't hit you

We had ZERO down time. It was from 1 live server to another. I'll check the permissions, but we copied the whole directories over using the SCP -r protocol.

Is there anything I should look for in particular??

What do you see in your Google Webmaster Tools account? Are they reporting any errors? Is there still active crawling activity?

There is activity... it seems to be coming back up as time goes by.... I'll keep an eye on it

Maybe it detected the move via the DNS propagation. I suspect it will rebound quickly. Keep us posted.
