Currently, the Secure Layer Certificate (SSL) for GoDaddy’s TDNAM appears to have expired.
When visiting TDNAM.com one sees the following message:
www.tdnam.com uses an invalid security certificate.
The certificate is only valid for the following names:
auction.godaddy.com , www.auction.godaddy.com , auction.godaddy.com , auctions.godaddy.com(Error code: ssl_error_bad_cert_domain)
It seems that GoDaddy – themselves a provider of SSL certificates, oh, the irony – failed to renew them! 😀
