FWIW, this YouTube video, on the Transport Evolved channel, is relevant. It's nominally about the Ford F-150 Lightning, but a good chunk of it is about maintenance problems that Electrify America is experiencing. In brief, the Transport Evolved reporters contacted EA and were told that EA is experiencing parts shortages that are causing delays to maintenance of existing stations. I don't recall if the video even mentions Francis Energy (probably not), but if EA is having problems getting the parts needed for repairs, chances are the other networks are, too. Tesla famously builds more stuff in-house, so they may be less impacted by this than others, although my knowledge of their Supercharger manufacturing is limited, so that's very speculative on my part.
