I was at the Fresno Supercharger when the Tesla technician was doing his diagnostic testing before the facility became available to the public. He had a small laptop computer with him that he used to test each of the stalls. He had a manufacturer's Tesla that he moved from stall to stall.
I got the impression that he was in direct communication with someone at corporate while he was doing his job. When he finished testing the final charging stall, he sprinkled the stalls with some holy water, chanted something in Latin, and said it would be a short time later when Tesla would "officially" announce that the site was open.
I checked on my touchscreen a few hours later, and Fresno was listed. I did not check the web.
