Let's Encrypt Data Center

I know Let’s Encrypt have 2 Data Center. You have own Data Center for Let’s Encryot or using IDC provided service like Colocation(e.g Private Suite)?

Not an answer to your question, but the CPS does talk about the facilities: https://letsencrypt.org/documents/isrg-cps-v2.3/#5-facility-management-and-operational-controls
