We do have a datacenter in the EU (Amsterdam) - and if you set up your account there you'll be able to transfer data to it. That's a popular destination for folks living closely to it, but even before that one went "live" we had lots of people using the our West Coast Data Centers without much issue. If you have a ton of data you can take a look at the Fireball (https://www.backblaze.com/b2/solutions/datatransfer/fireball...) which allows you to rapidly ingest data to us.

What are you using as TCP congestion controller? BBR should provide better utilization on long pipes (e.g. transoceanic transfers if stuff isn't geo-replicated). Totally anecdotal, but it helped me FTPing data from the US to europe.

Yev here -> This question's beyond me, lemme see if I can get a dev on the line :D

*Edit - sounds like BBR is used in some of the environment!

(I need to quickly ship a 50mb file to 50,000 clients worldwide.)

Hey Michael, I host RAW photos I want to share inside B2 (48mb each), and then put CloudFlare in front of it using their tutorial [1]. It gets edge caching, and achieves 200-500mbps. Its great, and I have absolutely no complaints.

@mherrmann - Only about 10-20GB, so not the TB levels you are dealing with, but backblaze isn't actually doing the transfer, it is CloudFlare.

@toomuchtodo - Yes, and on top of that, both B2 and CloudFlare are completely free since I'm under the 10gb storage limit (for now), and i'm a personal user of CloudFlare(for now).

Is your outbound data free because of the bandwidth alliance deal Cloudflare has with Backblaze?

Thank you; and how much data are you transferring each month?
