There are so many questions this leaves unanswered:
- Was this a one-off error in Cloudflare's processes? (These things happen on a big enough scale.)
- Were you violating a specific clause of Cloudflare's T&C? How clear was the clause? What did you do to fix this?
- Was the issue that Cloudflare estimated that you're not paying enough given the bandwidth you're consuming? Did you end up signing up for the Enterprise plan?
Transparency would benefit both Cloudflare (in not making people unnecessarily apprehensive about becoming/remaining a customer) and you (in demonstrating that you're handling this issue in a professional and responsible manner).
Sales over the phone (was fastest) told me that it's good I contacted as otherwise in 24hours my account would be fully banned(whatever it means) and that they will prepare me an offer in 15 minutes, but it was taking longer (no response after an hour or so) and in the meanwhile I wrote Twitter and HN post which CTO of Cloudflare noticed and then after a while I've got another phone call from sales that I should update my ticket to ask unbanning my account as it was approved now by CTO which I did and that solved the issue at least for now - and that's it - no further info what the issue was, still waiting on Enterprise plan quote for me.
The only sales guy who called me back before the CTO got involved was Kingsley Okoroh out of their UK office. I’m in the states. He even had no idea why no one in the states would call me. Anyway, Kingsley tried hard to help, Kingsley should be their head of sales since no one else cares.
Someone ringing up to say "I need a quote for this level of usage as I think I'm into your enterprise tier" might be asking for a smaller quote than the Big Fish the BDR has sent a cold email to who's eventually been convinced to take a meeting, but they're more likely to convert and unlikely to take lots of meetings or a particularly skilled salesperson to do it...
