100% Network Uptime Isn't Wishful Thinking, It's A Guaranteed Reality
We know that every second your network is down you're losing opportunities, revenue and the confidence of your
users and visitors. So we decided to do something about it. We designed and built the Zero-Downtime Network to
minimize downtime and we are so confident about its capabilities that we guarantee we will give you money back
if it goes down. And it works so well that we guarantee it.
Our 100% Network Uptime Guarantee—Every aspect of our Zero-Downtime Network makes it real:
- We use the network only for our customers' hosting needs, never sharing it with
telecom services or cable TV services that would negatively affect your service.
- The only bandwidth we use is high performance bandwidth, which usually isn't the case with
cheaper hosting providers.
- To provide multiple redundancies in the flow of information to and from our data centers, we
partner with nine network providers.
- Every fiber carrier must enter our datacenters at separate points. This is to protect you
from complete service failures caused by an unlikely network cut.
- You get the fastest and most reliable network connections because our Proactive Network
Management methodology monitors route efficiency and end-user performance, automatically improving the
network's topology and configuration in real-time.
- We purposely underutilize the network, making it resilient to even the largest Internet
routing issues.
- The network's configuration, co-developed with Cisco, guards against any single points of
failure at the shared network level. We even provide you with the option to extend it to your VLAN
environment.
- Cisco and Arbor Networks continually work with us, creating ever-improving ways of monitoring
and securing our network.

If we didn't own and operate our four US and four UK data centers, we could never engineer them to the standards required
to support the Zero-Downtime Network. We engineered them to never compromise security or redundancy. Ever.
Physical Security
- Keycard protocols, biometric scanning protocols and round-the-clock interior and exterior
surveillance monitor access to every one of our data centers.
- Only authorized data center personnel are granted access credentials to our data centers. No one
else can enter the production area of the datacenter without prior clearance and an appropriate escort.
- Every data center employee undergoes multiple and thorough background security checks
before they're hired.
Precision Environment
- Every data center's HVAC (Heating Ventilation Air Conditioning) system is N+1 redundant. This
ensures that a duplicate system immediately comes online should there be an HVAC system failure.
- Every 90 seconds, all the air in our data centers are circulated and filtered to remove dust
and contaminants.
- Our advanced fire suppression systems are designed to stop fires from spreading in the unlikely
event one should occur.
- All cables are securely tied down with cable racks suspended from ceilings, providing dual
routes for all cables.
Conditioned Power
- Should a total utility power outage ever occur, all of our data centers' power systems are designed
to run uninterrupted, with every server receiving conditioned UPS (Uninterruptible Power Supply) power.
- Our UPS power subsystem is N+1 redundant, with instantaneous failover if the primary UPS fails.
- If an extended utility power outage occurs, our routinely tested, on-site diesel generators can run indefinitely.
Core Routing Equipment
- Only fully redundant, enterprise-class routing equipment is used in Rackspace data centers.
- All routing equipment is housed in a secured core routing room and fed by its own redundant power supply.
- Fiber carriers can only enter our data centers at disparate points to guard against service failure.
Network Technicians
- We require that the networking and security teams working in our data centers be certified. We also
require that they be thoroughly experienced in managing and monitoring enterprise level networks.
- Our Certified Network Technicians are trained to the highest industry standards.
