Infrastructure
Two mirroring systems in Texas and Delaware
Our primary production servers are hosted by The Planet, one of the largest dedicated server hosting providers in the world (second only to IBM). The Planet owns and operates six state-of-the-art data centers supporting more than 40,000 servers, and fully redundant Network Operations Centers in two cities (Dallas & Houston) with 24x7x365 monitoring. It is one of the industry’s fastest, most robust networks (100 gigabits/sec).
Total Redundancy
No single point of failure that could cause prolonged downtime or data loss
XISOX system has total redundancy built-in to all services, meaning that there is no single point of failure that could cause prolonged downtime or data loss to a customer. Some highlights of our built-in redundancy include:
Geographical complete system redundancy: XISOX is fully implemented on two completely separate systems, utilizing different hosting companies, datacenters and networks. The primary production system is located in Dallas, Texas, and the standby system is hosted in Delaware. The production databases are replicated (mirrored) to the standby system at least twice a day. In the unlikely event of a natural disaster, terrorist attack or other such cataclysmic event in Texas, XISOX will be up and running from Delaware within an hour.
Backup redundancy: Primary production servers are backed up every day in three different ways:
  • The database server is backed up every day into a NAS backup system (a separate special backup server on the local network).
  • All production servers, including the database server, are backed up incrementally, at least daily, by a fully automated DiskSync backup system that sends the backup data to another, geographically separate, Dallas datacenter.
  • The database is replicated at least twice a day to XISOX standby servers in Delaware.
Network redundancy: For our primary production servers we don't just utilize two transit providers, but eight Tier 1 telecom providers, ensuring you'll always be able to reach our network at high speed.
Physical redundancies in datacenter infrastructure and hardware: We host our servers in state-of-the-art, world-class datacenters equipped with every imaginable redundancy in servers, switches, monitoring, power supply, air conditioning, fire suppression, and security. Our servers are equipped with multiple hard drives on IDE RAID drive controllers. All data on the server is always simultaneously saved on two or more hard drives. If one drive fails, the other drives take over without any interruption.
Security
State-of-the-art datacenter security and SSL encripted communication
Physical Security of the data centers include 24x7x365 on-site security guards; CCTV digital camera covering the entire center; building perimeter bounded by concrete bollards/planters; silent alarm system linked to law enforcement; redundant HVAC (Heating, Ventilation and Air Conditioning); multi-zoned, dry pipe, water-based fire suppression system with sensory mechanisms to sample air and provide alarms prior to pressurization; UPS systems and emergency backup diesel generators with redundancy built into all power backups.
Data Security is ensured by all server-client communications being transmitted through a secure (SSL) server. This is the same type and level of security used in internet e-commerce for securing credit card transactions.
Networks
Eight Tier 1 telecom providers and direct Internet connections
The Texas data centers 24x7x365 redundant monitoring from two Network Operations Center (NOC) locations, staffed by certified system administrators and security professionals. The network management teams operate NOCs in Houston and Dallas to assure the most sophisticated and comprehensive systems monitoring, and complete monitoring back-up in the event of any emergency.
Redundant network cores in multiple data centers means that if a router or high-level network appliance goes down for any reason, there is no loss of service. Gigabit cross-connects between multiple data centers assures that data moves quickly, and if any one data center were to experience network connectivity issues, it would simply route outgoing data through other centers. The system automatically measures the latency of key network routes and sends client data to the Internet along the best possible route.
Our XISOX primary production servers are connected to multiple Tier 1 telecom providers and direct Internet connections, bypassing transit networks and shortening the network path between our servers and your local broadband provider. The result is lower latency, maximum speed, and unsurpassed reliability.
The bandwidth providers are:
- AT&T
- AboveNet
- Savvis
- Verio
- Global Crossing
- Time Warner
- Telecom
- Cogent
Quick FAQs
  • We are located in the Northeast. Don't you have servers closer to where we are?
  • Why do you need redundant servers in another state?
  • How long will it take to switch over from primary to standby servers?
  • When the database is restored from a backup, wouldn't some of the most recent data be lost?
  • Can I check how fast is the connection to your server?
