What is colocation
Colocation (or 'colo') is the service of renting space in a data center to host your own servers and network gear. You own the hardware; the provider delivers the infrastructure — redundant power (UPS + generator), precision cooling, high-speed networking, multi-layer physical security and engineering staff on site.

How colocation works
1You already own — or purchase — your servers.
2Choose a colocation plan by size: 1U, half rack, full rack or private cage.
3Ship the server to the data center (the provider can help transport).
4Engineers rack the server, connect power and network, and bring it online.
5Access your server remotely (SSH, IPMI) or visit the data center in person.
6The provider monitors power, network and temperature 24/7 and alerts on issues.
