Finally all deactivated accounts were activated and everyone received apologize email from Apple. You were mistakenly sent an email informing you that the legal entity associated with your Apple Developer account matched a restricted region. Your legal entity does not match the restricted regions list and we have corrected the error.  Your developer account is now active and any associated apps and in-app purchases are once again available. No further actions are required on your part. We apologize for any inconvenience this may have caused you.

It looks like Apple started fixing the problem. Some accounts which were deactivated yesterday already active now. Thank you Apple!
