The certificate presented does not work for stackpromos.com, leading to a warning in my browser about an invalid certificate.

Invalid certificate for stackpromos.com; issued to *.stackexchange.com

  • Ah right, I misremembered what the core of your report here was. :) Issuing a valid cert for that domain is planned on the SRE team, but there's no ETA at the moment.

My bad.

Word on the street is stackpromos.com probably isn't supposed to have a valid cert, but I linked it in the blog post as https out of habit. Will fix as soon as I can get the blog post edited!

Update: Fixed.

    @rogerdpack There not being a cert is by design - the error that I fixed was linking to https in the Winter Bash blog post, leading everyone on a certificate wild goose chase.

    The SRE team has "add a cert to stackpromos.com" on their list, but it's not high up on the priority list at the moment since the domain is basically just a read-only museum of past promos, if you will.

We now route this through another provider for the redirect and serve a valid cert. Sorry it didn't happen immediately - it was a "minor" domain and just wasn't the highest priority at the time.


This is no longer relevant, since stackpromos.com domain does not exist anymore, and redirecting to https://contests.stackoverflow.com instead, which being part of stackoverflow.com domain, gets its https cert.
