This. I got excited about this until I came to HN and started reading the comments. I _have_ to have a cap. I don't want to do something stupid that puts me on the hook for $$$.
So who are you using then? I don't see anyone that has a cap. Everyone charges you if you go over your allotted bandwidth.
Not sure if this is still the case. Digital ocean had a pricing structure for bandwidth, but was not charging for that used bandwidth because they did not have a way to show how much bandwidth has been used in a billing cycle. Best to ask them if this is still the case.
