Well, from what I can see, having actually visited the site and talked with people working on the site, what is left to do is to commission the equipment, and that's Tesla's job to do. Construction is visibly complete (at least outside the charger enclosure which was still wrapped the other day) and there is power to the Fortis transformer.
Do recall that it is the Christmas holidays, and reasonable companies who appreciate their employees tend to be more lenient with family time over last week and this week. It's not like a delay of a week or so in starting up a new supercharger is critical at this point.
But, who knows, maybe it (the supercharger) is up and running as I write.
