Backblaze's B2 is cheap - but if your'e using them in production you must include these costs:

* their weekly 2 hour maintenance window 11:30-13:30 PST (which usually has no downtime, but sometimes is a full outage in the middle of the US day)

* having to file support tickets when your error rates increase above a usable threshold (for us about once a year for the last few years)

* support which does not look into the issue, just asks tons of questions as if they do not have error logs or any visibility on their end

* false success on uploads where B2 says it successfully saved your file but it is 0 bytes on their system (ALWAYS verify the upload despite B2's success code)

* extended outages if there's a high severity CVE (ex: they shut down for 10 hours for the Log4j2 CVE)

They have the best price - but when comparing options, it is simply not a directly comparable product to more mature cloud storage services.
