Wrong SSL certificate when accessing githubusercontent.com

Half the images on github look broken because they come from avatars2/avatars1 and the certificate is incorrect.

https://avatars2.githubusercontent.com/u/43192810?s=60&v=4

It’s funny because avatars0, avatars3, avatars4 etc seems to work.

https://avatars0.githubusercontent.com/u/43192810?s=60&v=4

I’ve updated my DNS to Google as well.

Actually found the answer using the dig command. It was my isp’s parental controls blocking avatars1/2.

So I removed parental controls and it was fine.

$ dig @8.8.8.8 avatars2.githubusercontent.com
