Web hosting

Technology - Overview

A seamless blend of UNIX and Microsoft™ technologies
HostSellers' web hosting technology combines the functionality of Windows hosting and UNIX hosting onto one platform. You can run ASP/MS Access and PHP/MySQL based sites from the same server farm. With our seamless blending of UNIX and Microsoft technologies, HostSellers' hosting system is truly cross-platform and one of the most advanced in the industry.

Scale to an unlimited number of domains on redundant servers
HostSellers' architecture and infrastructure was designed and built from the ground up to scale to an unlimited number of domains. These domains are hosted on multiple redundant servers, which are clustered using load balancing hardware.

Multi-Homed Network utilizing latest BGP technology
Our implementation of intelligent routing, coupled with the industry standard BGP (Border Gateway Protocol) peering, removes commonplace ´hot potato´ routing where packets can sometimes move further away from its destination. Our network technology robustly transmits data with the least possible latency.

HostSellers employs multiple routers and load balancers
Our multiple routers are made redundant through the use of Cisco's HSRP (Hot Swappable Router Protocol). Our server clusters use multiple load balancing hardware, designed for failover in the event of a load balancer fault, which allows us to give you 99.9% Uptime Guarantee!

RAID Storage Provided by Network Appliance
Data integrity and speed are assured by multiple Network Appliance Filers using RAID technology. This assures reliability where the RAID (Redundant Array of Independent Disks) allows an increase in the mean time between failures but also increases fault tolerance through a large data capacity and by placing data on multiple disks. This configuration allows I/O (input/output) operations to overlap in a balanced way, improving performance. Three back up systems are in place, one being on-site and two off-site at geographically separate data centers. All systems are monitored 24/7 by experienced NOC staff.

Peering Strategies
HostSellers' peering strategies (including those to Tier 1 backbone providers) allow us to share the digital distribution architectures of our peers: Sprint, AT&T, Cable & Wireless, Telus, MCI, and AOL.

These peering relationships also interconnect at all major public exchanges, including Mae East, Mae West, PAIX, and other popular NAP´s (Network Access Points).

Perimeter Security via Multi-Tiered Firewalling
Servers are protected with software-based firewalling at source and destination addresses, and source and destination ports. Our systems are secured using the latest security methods including router access list filtering on inbound carrier feeds and firewalling at the SYN level on internal devices. Security systems, including firewalls, are tested on a monthly basis. We use security scanners that are automatically updated instantly with the latest exploit/DOS check codes. This provides us with an accurate and detailed report on our systems.

Our security team subscribes to all the major security mailing lists, including BUGTRAQ from These lists provide access to the latest security information, which enables us to patch newly found exploits within hours of their discovery.
