There seems to be a big list of domains streaming through in alphabetical order. First there were dozens all starting with J, now there are dozens starting with K. Looks like gemalto is going through the day's domains in alphabetical order and adding them one at a time?
Yeah, it's interesting to see how certs are issued from the larger lists, since they tend to come in a deluge. This goes doubly for the cloudflare SNI certificates for their edge nodes!
