I am uncertain about which group this topic belongs in.
Neustar Inc. provides a free domain evaluation service called “UltraTools”. This company (whose common stock is traded on NYSE), would appear to have some claim to internet expertise. According to Wikipedia, it is “a provider of clearinghouse and directory services to global communications and internet industries”, and also is registry for several top-level-domains.
So, what does this have to do with Let’s Encrypt?
I registered for a free account and asked for a scan of my main domain. The UltraTools scan red-flags my site’s Let’s Encrypt certificate as not valid because “certificate has been revoked”. (The certificate is accepted by every major browser without any issues.)
Does anyone else see the same issue? Is this anything I should be concerned about?
