Just saw these all over parking lot entrances to the Westlake, California Promenade that the Tesla Superchargers were unavailable on Th. 5/13/21. Not sure how long they have been up but the signs look pretty official to be for a one day problem, IMHO. I went to the chargers (about 25 of them) and nobody charging but no signs from Tesla as to what is the issue. Anybody with ideas?
