Yeah I think since the fiasco they've suddenly been bandying about "Oh you have until August 23rd, there's no rush guy just chill okay" but that was after months of "If you don't fill it in on August 9th we'll fine you $180/day" to try and shut down people calling for boycotts after the changes they shoved through the week before Christmas that allows them to keep the data linked to everyone's name for 4 years.
That was certainly one mistake. How they overlooked the fact that almost everyone was going to get home, eat, and then hit the Census site afterwards, beats me. It was a prevailing theme for everyone I know, sitting there refreshing and then making fun of it all on Twitter.
