INFRASTRUCTURE & UPTIME
99.997% Uptime, and How We Keep It
1.54 MW of power fed by three utility substations, air cooling with chillers and commercial HVAC systems, multiple carriers in the building so you're not tied to one, controlled access and continuous monitoring.
What Keeps the Lights On
Sierra Data Centers' uptime is 99.997%. That comes from the building and the people who run it:
- Power: 1.54 MW, fed by three utility substations, with expansion capacity through Duquesne Light (DQE)
- Cooling: air-cooled with chillers and commercial HVAC systems
- Carriers: Verizon, Lumos, DQE Communications, Cogent, Metro Optical, Fidium Fiber and more in the building
- People: continuous monitoring, and support 24/7 through on-call engineers
Fewer Single Points of Failure
Three utility substations feed the building, so it doesn't hang on one. Several carriers share the building, so you can run two diverse paths. And if you keep a recovery copy at our Metro Columbus site, a regional event in one city doesn't take out both.
What 99.997% Means in Practice
99.997% uptime works out to roughly 16 minutes of downtime across a full year. Our SLA commits to 99.99%, and the uptime record has run ahead of it.
