Thats not true. Am in texas, the site opened exactly 11.00pm my local time. my 11:00pm = 12:00am ET.
On May 1 when the results were announced, I tried to check at 5am EST, but it kept saying to come back. Finally, it was opened at 6am EST.
I know the new day starts technically at midnight (12am EST), but the DV results page opens at 6am EST. I hope you'll not sue DOS for being off by 6 hours.
