DV-2019 Selectee from Tanzania

From your date of notification that you've been selected to be precise?
You mean when I filled the DS260? I had done that in June 2018 but had to unlock in November and again in April to add some information. I was asked for documents in January I think and was told they were ok after 5 weeks.
Like Susie said, I don't think glean any useful information from this since the new procedure of providing documents made rather a mess this year.
