First and foremost, I would like to commend @@Britsimon for all the goodwill he is doing in these forums. I have been a member for quite a while and even though I have not been posting anything but I've been a regular viewer and an ardent reader of Britsimon's posts. Besides putting up with people's critism and insults, this gentleman has quite some energy and may God bless him!
My (optimistic) opinion is that, as a programmer, I think of one possibility; they have setup everything correctly but they probably have not linked the queries into the DV 2016 database. Specifically, I think that they have the queries directed to the DV 2015 database hence all confirmation numbers will be given a NOT SELECTED notice. What they need to do is just correct that and we will all get proper results. For DV 2015, of the people I had submitted applications for, one was my nephew's. When I checked on the 1st of May last year, his was NOT SELECTED and then after they sent an email to all applicants to recheck the status the next day, he was RANDOMLY SELECTED! Therefore, I think the query was the case last year and it is the case this year.
I have been applying for DV since 1993 and only skipped DV 2005 (the first online DV) and have still not been selected. I lived in the US between 1998 and 2002 as a student, so I know why I would like to go back and live there - its a beautiful country with lots of opportunities. Therefore, I'm already immuned to the disappointment of NOT BEING SELECTED! However, I'm still a hopeful.
Therefore, my fellow hopefuls, understand Britsimon when he tries not to give anyone unconfirmed hopes. He is only protecting you and himself. If there really is a technical glitch, it will be corrected (believe me, Americans are thorough), and appropriate action will be taken to correct the situation. However, in the meantime, if our fates say that we are NOT SELECTED, then let's accept that as reality and move on with our lives. If any corrections will be made, they will officially communicate through email.
All the best to everyone!
