Was this in the past week? Because just a few days ago I was experiencing a similar problem. I attempted to access https://rememberthemilk.com and chrome complained about the SSL cert, as I was receiving the cert for their CDN and not for rememberthemilk itself. I couldn't find anyone that could reproduce the issue, but it occurred consistently on my computer regardless of browser. It resolved itself 20 min after I first noticed it, but I'm still really curious as to why it happened in the first place.

Usually the CDN will have a single certificate which then has multiple SAN entries. What can happen depending on the size of the CDN is it can take a long time for the SSL to be added to the SAN entries on all the edge servers. So if a site just starts moving to a CDN they sometimes jump the gun and instead of waiting for all the edge servers to have the SSL they just change DNS records.

You then have a scenario where the DNS is waiting to propagate and the SSL is still propagating around the CDN. Hence you get soem users without a problem, some with and it eventually all clears itself up.

Yeah - happened on Tuesday and was cleared up the following morning.
