GCE rolled out the new ARM64 instance family, namely C4A [1]. We're currently using T2A, which has both limited performance and availability. We should replace the latter with the former. As a potential bonus, given a better price/performance relative to n2-standard, we could see a small reduction in cost by ramping up metamorphic-arm64-probability in the nightlies.
