Here is the scenario: I had a Virtual Private Server (VPS) with 9 websites on it that were all interlinked. It worked great for awhile. Then in Nov. 2004, Google did a big adjustment, and all 9 of my sites dropped out of sight.
My question: Do you think my 9 sites were red flagged, or was it my VPS and any websites hosted on it?
In general, the hosting company shouldn't make a difference. It would be very rare for it to cause a problem, and if it did, it would be mostly due to the host having a lot of downtime, making the website inaccessible.
While it's hard to say for sure, the fact that 9 sites were interlinked on the same server probably made it appear spammy, as if there was only 1 owner "voting" for all his own websites. Since Google counts links as votes, it wants to count only real votes, not fake ones.
But that's really just a guess; it would take some in-depth research to determine the exact cause. There are often technical reasons that can be uncovered with a bit of digging.
