Is Server Banning Possible?

[PunkyLZ]

I was just wondering if an entire webserver can get banned by Google? I ask this because as I've mentioned before my number one ranking sites across the SEs have all dropped out of the Google/MSN/Yahoo! rankings. The only thing they all have in common are the webserver that hasn't had any downtime in the couple months! The sites rarely come up for their a search on company names and domain names and if they do it's on the second or third page of results!

I don't mean to whine, but I'm the one who's taking the heat from management and the clients and I do not have any answers other than it's out of my control. I mean really it is...it's up to the SEs!

Thoughts?

IP addresses have been banned. BUT, bans are rare.

it's out of my control. I mean really it is...it's up to the SEs!

It is generally within your control.

Wwat is the URL and what arethe keywords?
