I discovered the problem on this thread: If time-travellers always arrive naked how and what would they trade?

In the comments, another user posted a link to another part of the site. I followed the link.

Here is the worrying message I got:

Your connection is not private
Attackers might be trying to steal your information from meta.worldbuilding.stackexchange.com (for example, passwords, messages, or credit cards). NET::ERR_CERT_COMMON_NAME_INVALID

Your connection is not private

The link is:


What is happening? Is Stack Exchange compromised?

The detailed error Firfox gives me is

The certificate is only valid for the following names: *.stackexchange.com, stackexchange.com, meta.stackexchange.com, stackoverflow.com, *.stackoverflow.com, stackauth.com, sstatic.net, *.sstatic.net, serverfault.com, meta.superuser.com, stackapps.com, openid.stackauth.com, *.meta.stackexchange.com, clc.serverfault.com, meta.serverfault.com, superuser.com

Note that meta.worldbuilding.stackexchange.com is not among the host names nor does it match any of the wildcards (recall that the * wildcard represents only one domain level!)

With a mild frown, I'd be willing to allow the security override in this case.
