Is OSHA-30 required at all DC operators? ▼

What is the easiest data center operator to get hired at? ▼
QTS and CoreSite have the lowest certification barriers. Both require only OSHA-30 as a mandatory credential for most trades, with other certs listed as preferred rather than required. They are good entry points for technicians building their DC resume before targeting Equinix or Digital Realty.
How often do NETA certifications need to be renewed? ▼
NETA Levels I through IV require renewal every 3 years. Renewal involves accumulating continuing education credits or retesting. Letting them lapse will disqualify you from Equinix and Digital Realty work immediately — both do background checks on credentials before site access.
