In what was widely viewed as a dress rehearsal for the future release of all 1 and 2 character .COM domains, Verisign put in a request in August for the same operation in .NET.
However in a surprise move, Verisign now seems to have withdrawn the request. This is what the ICANN registry service request page now shows.
No information as to why is listed. Verisign may obviously resubmit the request at a later date so at this stage, it is impossible to determine what effect, if any, this might have on the 1&2 character .COM release.
