Ah yeah, this one - 11 days.
If I remember right, it started with the move from Akamai to Cloudflare (New CDN for the Production API), where they went from relying on the CDN to terminate SSL, to doing it themselves.
I was originally going to say that your conclusion was a little overblown, but now that I think about it, that migration could have been a bit smoother 
.
Edit: another interesting thing is that OCSP is still on Akamai. If it had been migrated as well, things could have gone real bad!
