Yes, and no. They estimated a slightly higher chance for a Hillary win over a Donald win, but they were well within the margin of polling error, and they have been for every election. Plus people have a tendency of over-valuing a "51% chance to win".
While this is good news, it could mean nothing.
EDIT: 538 explained it better than I ever could:
"Statistically, too, there is no meaningful difference between a 50-in-100 chance and a 49-in-100 chance. Small changes in the available polling data or settings of our model could easily change a 50-in-100 edge to 51-in-100 or 49-in-100. That’s all to say that our overall characterization of the race is more important than the precise probability — or which candidate is technically ahead.”
Apart from the jetlag it's not too bad, actually. I've had worse jobs that didn't take me to the far corners of the world.
