comment How to understand details of CPU usage
I tried to attach to one of the dispatch processes and here is a sample output: pastie.org/9532757. It is interesting, that even if there are no requests (records in access.log and output in strace) this process also has more than 30% in top.

comment Dozens of apache processes with empty access.logs
Thanks, mattias. I was able to resolve it with netstat. There were hundreds of connections to apache from the same IP, looks like it is a kind of DOS attack when connections are opened and nothing is requested.

comment Use two website hostings for better availability
Thanks, Jens! Today I see Route53 and looks like it is nice, but, yes, I agree that DNS caching could be a problem (especially for short time outages).

comment Use two website hostings for better availability
Yes, I originally used one VPS from Dreamhost for years. Now I have another one for some tests and I want to use them somehow together to provide higher availability. And I don't want to migrate all this stuff to Amazon yet.

comment Use two website hostings for better availability
Yes I see, but according to description "across multiple Amazon EC2 instances" it is for balancing between EC2s, and I don't use it yet.

Yes I see, also looking in Amazon services. Thanks again for your answer!

Christopher, thanks for your comment, looks like I need at least two load balancers for it. Now I'm trying to understand, is it possible to use any service-provided load balancer (like Cloudfare) with my VPSs.
