According to their FAQ, they're still running primarily out of the single DC [1]. However they did post on the blog that the new DC was online as of June 2017 [2]. I run Backblaze (backup) for Desktop but also have a local NAS that stores copies of critical items. That NAS also serves bulk storage (like old Premier Pro projects) which is backed up to B2. So critical data follows 3-2-1 backups [3]. Desktop, NAS, Backblaze. Less critical bulk data is only 2 copies, NAS & Backblaze B2. That's a really long way of saying that 1 remote datacenter is enough for me. My data is important to me, I'm a digital packrat, but the likelyhood of something taking out my home (SF Bay Area) and Sacramento (Backblaze DC) ... likely means TEOTWAWKI [4] - and my data will be of very little concern then. Caveat. I'm just a person. Not a business. If you're a business using B2 for backup... you probably want to worry more about multiple AZ/Region storage.
