In addition to the good point raised by @jcreedon regarding their single datacenter (which I think is a bit of a bigger deal than he does, primarily because I don't think it scales linearly per-GB for the first few datacenters, though it might thereafter), I'm more concerned about the bandwidth.<p>There's no talk about their backbone or their network capacity. I get that they have terabytes of upload coming in, but as anyone who's used their software can tell you, it's throttled. I don't know how many users they have to tell you how much bandwidth they're actually handling, but can they handle people using B2 as a distribution point for large files for customers? For example, I have a huge S3/CF monthly bill from customers downloading ~400MiB ISO images tens thousands of times a month. Amazon CloudFront is ~$0.085/GB for the first TB, while BackBlaze B2 is an incredible $0.05/GB - but at what performance? Will my technical support representatives be getting angry phone calls about halting download speeds or do they have the capacity for something like this?<p>Hosting the world's data is no tiny task, I hope they're ready for it and I do, truly, wish them all the luck. I've been a BackBlaze customer for a few years now (at least 5 or 6, I imagine) as a tertiary or quaternary backup (haven't had to restore... yet), and B2 looks and sounds promising, but as far as technical details go, this post is nothing.<p>EDIT: In response to the reply below, I believe it's throttled by default in the client, though that can be turned off in the application settings. Also, you've replied to my claims of throttling but have ignored my question regarding backbone capacity and network readiness...
