> Last I checked, Backblaze still stores most data in 1 location, no?
Backblaze now has multiple regions! One in Europe (Netherlands) and one is called "US-West". Quietly the US-West is actually three separate data centers, but your data will only really land in 1 datacenter somewhere in US-West based on a few internal factors.
To be absolutely clear, if you only upload and store and pay for 1 copy of your Backblaze B2 data, it is living in one region. To get a copy in two locations you have to pay twice as much and take some actions. So if this kind of redundancy is important to you for mission critical reasons Backblaze B2 would only be half as expensive as one copy in Amazon S3, not 1/4 as expensive.
In the one copy in one region in Backblaze B2, any file is "sharded" across 20 different servers in 20 different racks in 20 different locations inside that datacenter. This helps insulate against failures like if one rack loses power (like if a power strip goes bad or a circuit breaker blows). But if a meteor hits that 1 datacenter and wipes out all of the equipment in a 1 mile blast radius, you won't be getting that data back unless you have a backup somewhere else.
I am fancying the idea to move our CDN from AWS stack to B2 + CF, thanks to Bandwidth Alliance. There's at least one thing stopping me: for simple schema of hosting static content out of bucket we should deploy Workers just for URL rewriting. Guys from CF recommending that way and not URL rewrites by simple rules[1]. But it puts us in a weak position of raising cost twice: for increased edge trafic AND for increased number of requests.
Can anything be done on BackBlaze side to address the problem, like custom domains for buckets? Like https://f001.backblazeb2.com/file/bucket-name/file.jpg => https://bucket-name.f001.backblazeb2.com/file.jpg ?
