In... fall, a year ago, IIRC, they were periodically using a different certificate / apparently their own certificate authority for Gmail. (I'm not sure I recall the underlying root, but I think it was different from "the usual one".) It looked like it might be part of some testing or since-rescinded initiative. Separately, for me Gmail continues to periodically include http references in the https-delivered web interface, causing the browser to display its corresponding "insecure" message/chrome. I wish they would just stop that: If nothing else, it's a bad lesson/conditioning for the average user.
