Introduction
					Our core network is based in carrier-neutral 
					datacentres; Telehouse Docklands
					houses our two key PoPs across buildings with connections to
					the London Internet Exchange (LINX) and London Access Point
					(LONAP), allowing us to offer customer ultra-reliable services
					no matter where they need to access it from. Our network also
					extends into Telecity Sovereign House
					and other Telecity datacentres. We have relationships with our
					key datacentre partners for over 15 years so we are confident
					in their standards.
					We connect our core sites together using three 
					diverse links which operate across physically separate 
					fibre rings with different hardware vendors for the most 
					reliable service. Our internal core network runs OSPF/OSPFv3 
					for quick failover in the event a link fails, and we use 
					BGP4 for multi-homed customers and peers.
					
					Trusted vendors
					Our core network is based on Juniper Networks and Cisco Systems
					routers and Arista/Cisco Systems switches.
					 
					Monitored rack power distribution units are sourced 
					from Geist and server power distribution is
					managed with APC Switched Rack PDUs which provide power 
					control for each outlet. We also use APC Uninterruptible 
					Power Supply (UPS) systems and Automatic Transfer 
					Switches (ATSs) in core network racks for additional 
					protection of critical equipment.
					APC environmental monitoring solutions are used for 
					temperature, humidity and door status for racks in 
					conjunction with Axis IP surveillance CCTV cameras. Our 
					cabinets in Telehouse are protected by Abloy Protec high 
					security locks which maintain key control.
					 
 
					 
					Cooper B-Line supply us with their Access cabinets 
					which provide for excellent airflow options within 
					different environments as well as easy access to the 
					side for maintaining tidy cabling.
					 
					For our internal use, we use a mix of Dell PowerEdge 
					and HP ProLiant servers.
					Internet Exchanges & Transit
					We have diverse connections to LINX Juniper, LINX Extreme
					and LONAP's peering exchanges in London, direct interconnects
					with many UK network operators as well as multiple 10Gbps
					transit connections to global Tier-1 networks putting quality
					and resilience at the top of our network priorities. These are
					based in different sites giving us resilience against a
					site-specific issue.
					By peering directly at the two most significant London
					Internet Exchange Points, we can ensure the best
					connectivity to the major UK broadband and global content
					networks. In the event that an issue arises, it also means
					we can liaise directly with the networks in question to
					resolve issues.
					Redundancy & Diversity
					We ensure that wherever possible, we introduce 
					redundancy into critical equipment, such as diverse 
					uplinks to different core switches/routers, dual power 
					supplies (fed from diverse power feeds where available), 
					dual UPS systems, automatic transfer switches, multiple 
					suppliers for inter-site links, using redundancy 
					protocols where possible, etc.
						
					 
						
					Independence
					We run an autonomous network (AS21396), which means that we do 
					not rely on any single supplier for our network 
					connectivity. If one of our transit providers switched 
					off their entire network, within a matter of seconds, 
					all traffic would be taking alternative paths. This also 
					means that we control our routing preferences, and 
					allows us to 'work around' problems in third party 
					networks when they cause issues for our clients.
					We also offer access to third party networks operated 
					by other service providers using different upstream 
					connectivity and thus have the ability to provide a 
					truly redundant service with a choice of using one or 
					two datacentres to add physical redundancy under a 
					single service contract and support facilities. 
					Monitoring
					We monitor everything. It is only by doing so that we 
					can be sure that we are delivering our customers an 
					unparalleled service. If a problem arises, we must be 
					alerted before our clients notice, and we endeavour to 
					fix problems before they impact on customer service. Due 
					to the redundancy in our network, most issues are 
					non-customer affecting. We have hundreds of individual 
					monitors in place to detect the earliest sign of a 
					problem developing.
						
						
						IPv6 Support
				Our network is IPv6 enabled and we can provide IPv6 
				transit and related services to customers. Find out if your
