Backblaze currently has data centers in Sacramento California, Phoenix Arizona, and Amsterdam Netherlands.
The region for an account, selected at the time of account creation, will determine what data centers may be used to store data for the account. The region for an account is available via the "My Settings" page of the Backblaze website, once signed in.
Accounts in our US-West region will store data in both Sacramento and Phoenix data centers. Accounts in our EU-Central region will store data in the Amsterdam datacenter.
