I notice a few blips now and then, too - it's visible on my graphs. Sometimes they can be as long as an hour or two. But then, I'm not getting any user reports in these times which makes me just wonder about the monitoring. I was having some major problems with a server that would flip out under heavy load. Turns out it was the specific kernel I was using. Linode support was quite helpful once I actually contacted them about it.
