I did a survey how common those load-balancing 'CDN services' are ('CDN service'
defined as 'hostname that sent cert A, then B, then A again'). See

Yes. Generally the result from above survey is that certpatrol's popup saying
'CA changed' is rather rare, and serves as a good indicator when user should be
aware that something may be amiss (i.e. low false-positive rate).

There's also bunch of services (server clouds) that issue new certs every 2-3
days. I'll try to post results in a day.
