Re: I've known this for a while
Now all I really want is a list of sites that don't work, so I can either avoid them or try to pressure them to update.
Unless you're referring to use of SHA-1 certificates in general, I think maybe you're missing the point; this article is about security devices between you and the internet that MITM your connection by generating their own SHA-1 certificates. In these circumstances every HTTPS site you try to connect to will be borked.
