Just want to mention this is mostly due to increasing awareness about bitcoin generally (as opposed to anything specific we are doing). People are getting really excited about bitcoin, which has been great for us and the community generally.
I'm shocked that months of running the service, and it's still very difficult to buy, and the only remedy is to try at specific times. It seems terrifically incompetent, despite the continual "we know and we're working on it!" line.
At the very minimum, you'd think you'd email customers that attempted a purchase to tell them you have capacity open. Or let them reserve. Or really, anything but what you're doing.
We are 3 people total, servicing 120,000 customers. We could start wait listing new users into the service, but there are many of them who get value out of the product as it is, so it doesn't feel like the right solution.
I still don't see why someone shouldn't be able to reserve a purchase, even if for a 15-minute time period. Or change the limit per-account so that more people can get a piece.
