I don't have a fleet of systems like Google but on the several few thousand servers I look over, I see the number of ECC errors is lower than that. It is however a strong power law distribution, many servers (>70%) see no errors at all, and a few have so many that they are unusable, some are in between and have undetected performance or other impact.
