2. It is clear that there was a lack of communication between the Foundation and and RS at least. viz:
2a. The RS registration page initially required that a company name be given. The form was rejected without it. The Foundation surely knew that many of the potential buyers were private individuals.
2b. The Foundation thought that RS would be taking orders. Evidence is the "wrong page" tweet.
I'm not party to what happened behind the scenes so I don't know how much of the fiasco was attributable to incompetence and where any blame lies. However I think that if the launch logistics had received 50% of the effort that went into the launch PR then things would have been substantially smoother .
I think these are all very valid points, and I've no doubt the Foundation will be taking things up with RS when the dust settles, if they haven't already.
From the evidence I've seen, both from Tweets made by people who'd spoken to RS, and other sources, RS had never intended to start sales on the 29th - the date was 5th March.
Whilst the Foundation may have told someone at RS to expect lots of traffic, I'm reasonably certain that message didn't get through to the numerous teams behind the scenes who manage the websites, servers, networks etc. I could post more details on that here, but I'd probably get in to trouble...
I too managed to register on the RS website at just past 6am, and have heard nothing since. No email, German or otherwise, in my Inbox or Spam folder. A registration my son did much later in the day did get an auto reply... RS's website states that those people who successfully registered, should have received an email by 2nd March - maybe one will eventually come, but in the meantime I've preordered with Farnell - whose website now at least seems to be in much better shape than it was on Wednesday !
