Yes, but it also says that the problem was at multiple supercharger stations. IMHO, this makes it unlikely that there was the same malfunction at multiple superchargers all at the same time. Rather, throttling by Tesla makes much more sense.

My car won't charge faster than 60kW

Did you even read this thread. This has been hashed out multiple times. Once again, that only states the charging was reduced by the supercharger and is not an issue with the vehicle. It says nothing about POLICY or it being intentional. Period.
Malfunction could be due to a new tech installing something incorrectly at multiple locations, or a bug in a revised part, or a new part revision that is installed/setup different from the old one. Any number of malfunctions could manifest at multiple locations before it becomes a known problem.
My experience was the Supercharger tech onsite said that he just replaced the splitter and must have done so incorrectly and that was why I was getting a reduced (<60kW) rate. When I switched to a different stall, no limiting, full 110+kW. Why would I be throttled at one stall and not another (at the same location, within 5 mins) if the policy was to throttle? More likely an Supercharger error, especially because it seemed his laptop connected to the Supercharger gave no indication of the problem. It was only when I asked that he became aware of the problem, and that he figured the issue was his recent installation not splitting the power to the pedestals correctly.

Inconsistent charging speeds at SC?
There's been a couple of times where I arrive at a station with very low SoC, good weather, completely empty, and then the charging speed limited to 60kw. I change stalls and then it's perfectly fine at 120kw. This has been happening for months...at various stations...various times during the day...and yes the cord is seated all the way.
I was thinking about it some more and I was wondering if Tesla uses stationary storage at their SCs to help offset high demand charges from the utility? Could it be possible that the slow stalls where because the station storage was depleted? And then the fast stalls had full stationary storage?
I pulled into Gilroy the other day...there's a meter on the side of the SC that shows the station pulling 8kw when no one is even there. I plug in my car and it shoots up to 130kw...which would suggest it is pulling all of that from the grid, which throws out my demand charge theory...what do you guys think?

I have seen that thread before(when it was only 11 pages, now its 51)...but the fact that I can always find a stall that will do the full 120kw leads me to believe that they aren't throttling on per VIN basis...and throttling by stall doesn't make sense unless it has a history of failure at higher rates?

Shoot the messenger, why don't you? 'ecarfan' was asking for the document that was being discussed so I simply posted the link.
I agree it says nothing about policy.
It's a two way street. At the same time, I should not have to find out about limitations on my car or policy changes here on the forums. Tesla needs to be communicating these things directly to customers. Believe me, they've screwed up before on this.
If there was absolutely no policy change that occurred and it ends up being some random issue then I say fine. If there was in fact a change then Tesla is merely showing that they've chosen to continue with their sealed lip approach when in fact they ought to be opening a dialogue with loyal customers.

Might it have something to do with half the chargers apparently having been installed upside down? 
Well, now I'm going to fan the fire and claim Tesla is limiting based on proximity to home...
Yesterday I charged at the new SLC, UT charger, limited to 55kW. Today, I changed my address listed on the mytesla account page to somewhere in New Jersey and went back to the supercharger. Charged initially at 100kW and as it tapered held 80kW. Used same stall both times.
Yesterday, mytesla address set to Utah:

Change you home address back and see if you are once again throttled. If so, that would be complete verification!
Not complete, but it's a good start.
We need to:
a) document more information such as time of day and day of week that it was done, mmh's patterns of charging (are you an occasional SC'er or a habitual local SC'er), car version, etc.
b) try and tighten the timeline up to narrow the variables (1 day gap leaves reasonable chance something else happened in the meantime...)
c) reproduce with other cars and SC's (probably one of the best first steps)
d) start looking for patterns that would explain why many owners in this thread have not experienced any reduction in rate given similar conditions.

I believe mmh saw what he or she saw with respect to the throttling, though I don't know what it means. What I don't understand is why, if Tesla really did want to throttle local cars, (and I am not yet ready to accept that premise) they would do so in a way that is so incredibly easy to circumvent. The car holds so much other information that could be used to determine where "home" is, that we wouldn't have any ability to change. Why use something we can change in 30 seconds?
Today I left my home location set, went to the Fremont Supercharger and I got the normal 118Kw start at 9% SOC. Not the 60kw I have been getting for a few weeks. I left visible Tesla up but it seems to have dropped out at the start of charge. Same time same place and I think the same stall (I was the only one there at the start (11 free stalls) and usually am the only one).
