Not only that, I see *two* certs issued for GitHub subdomains plus the parent 


Why wasn't this additional cert identified and disclosed prior to the 
aforementioned list being posted? It seems a no-brainer to manually audit the 
list for obvious cases of mis-issuance (i.e. not only the domain was not 
validated, but the customer clearly has no ability to validate it if asked).
