About Web Africas Servers

International

The datacenter utilizes the Enterprise routing and switching engines from Juniper and Cisco. Utilising Juniper M20 routers as border routers, Cisco 6500 series switches in our distribution layer, Cisco 6500 and 5500 switches in our aggregation layers, and Cisco 3500 and 2900 series switches at the customer layer. Our network is fully meshed and redundant with 8 backbone providers. The network consists of UUNet (GigE), Sprint (GigE), Level 3 (GigE), Global Crossing (GigE), Verio (GigE), Time Warner (GigE), Allegiance Telecom (2 x GigE), and AboveNet (2 x GigE).

	The entrance to the datacenter is comprised of badge-keyed doors that are monitored by our internal tracking system as well as closed-circuit cameras, ensuring that no unauthorized entities may enter the premises.
	The datacenter spans more than 60.000 square feet of raised flooring with multiple AC units maintaining a constant ambient temperature of 70°F. Among the long list of datacenter features are a comprehensive VESDA smoke-detection system, multiple UPS systems to protect against power outages, and multiple generators to ensure that customers are unaffected even in the event of catastrophic power failure.
	Boasting over 100 individual motion-sensitive closed-circuit cameras. The security system quite literally follows each visitor throughout our facilities until they have concluded their visit, and this information is routinely audited.
	The power system was designed for maximum redundancy, ensuring servers will never be unavailable due to a power outage.
	The datacenter utilizes 6 – 500KVA Powerware UPS units for battery backup power in emergency situations. Each unit comprises 160 batteries each for a grand total of 960 batteries and 80 minutes of runtime. The UPS units operate in failover pairs extending the redundancy and runtime of the battery backup units. All UPS units are monitored via DATATRAX™ with information distributed to the NOC facility in real time. These units are also monitored via NOC Engineers 24/7 by physical inspection every 4 hours.
	These automatic transfer switches transfer power automatically during periods of electrical failure to any of our three electrical grid feeds. The transfer switches automatically transfer power between the power grids, the UPS units and our diesel generators without power interruption. All environmental systems are monitored via our DATATRAX™ monitoring system and any variance in systems is reported immediately to our NOC facility.
	The datacenter's electrical infrastructure is broken into three primary zones within the datacenter (A, B, C). Zone A services ½ of the datacenter with electricity. Zone B services the remaining ½ of the datacenter and Zone C overlays the entire datacenter creating a complete redundancy in electricity allowing for the 100% uptime SLA. Our north generator is a 1.5 Megawatt – 16 cylinder diesel generator sitting atop a 2500 gallon diesel tank. This generator supplies electricity for zones A and B and has a maximum runtime of 15 days with onsite fuel. Offsite fuel contracts have SLA requirements of 4 hours for a refuel. Diesel generators can run indefinitely and are monitored by our DATATRAX™ monitoring system.

All the servers are housed in UUNET's Cape Town Data Centre.

A simple adherence to WorldCom standards has resulted in one of the most advanced data centres in the country. UUNET SA's Cape Town data centre house state-of-the-art hosting facilities in environmentally sound conditions. The driving consideration behind UUNET SA's multiple hosting facilities, redundant infrastructure and ample bandwidth is optimum content delivery.

Apart from the physical security provided, UUNET SA also requires hand print recognition for entry and subject all data centres to constant multi-camera surveillance.

UUNET's data centre is further equipped with:

redundant infrastructure
redundant and diversely routed bandwidth to the UUNET backbone,
direct links to local and international peering points
air conditioning
secure cabinets for hosted equipment
fire alarm and suppression systems
uninterruptible power supply (UPS), back-up generator, and
fire protection and protective cooling systems.
The data centre is designed to withstand catastrophical disasters - from flooding to fire, using various failsafe means such as raised floors, back-up generators and fire-suppressive gas.
