In my opinion, not likely. As far as we know, the FastLane update was purely to switch account log-ins over to the new NSF ID system, and any hypotheses that it involved the GRFP results was just speculation (not that speculation is bad). I fully expect our old friend the maintenance advisory to accompany the results release - of course, I'd love the NSF to prove me wrong.
Me shouting into a megaphone outside the White House: "Donald ya want a historic presidential legacy? Sign an executive order to start releasing the GRFP results on a Friday night!"
Starting to feel like I'm Charlie Brown and the NSF notification people are Lucy pulling the football away every time! Fingers crossed that results will be out soon.
For what it's worth, I had also emailed NSF a few days ago and they responded with the exact same message about early April, word for word; I really believe it's their stock cut-and-paste response that they use every year, including past years when results have been posted mid-to-late March.
No idea when results will be out but definitely hoping for this Tuesday! Though it worries me that there's still not a Fastlane maintenance alert for Monday night yet, like there has been for previous years based on their forums.
