Run a local dns server on each node, and have resolv.conf point to localhost. This would work, but it would give us a lot more services to monitor and manage. FWIW, this is the only workable solution that I have found for this problem. You do need to restrict the server to only listen on localhost, but it has completely eliminated users noticing ...

If you're getting a service where you're not dealing with the physical infrastructure, you probably don't care about where that physical infrastructure resides (so it's probably ...

In addition to Chris's answer about CP, I'd point out that the way the big guys handle this is: Using databases containing hashed values of known bad material This isn't even a particularly effective solution, because the slightest change changes the hash They will generally, or often maintain their own database, in addition to any publicly-accessible ...

There are various Government and Industry programs that will provide Hashes of "Known Bad" material (eg CP) to hosting providers. You can then hash the files on your servers and compare.

They do, but you need custom engineered components, OVH (one of the biggest datacenter company in the world) are using water-cooling for more than 10 years. Check out this link where you can see their racks : http://www.youtube.com/watch?v=wrrZxmfevoE The main problem for classic companies is that you need to do some R&D to use such technology.
