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
