At Telecoms Cloud, we operate one of the biggest and best cloud telecommunication networks in the world, run across multiple international secure sites with extensive physical and network security. Instead of needlessly and expensively reinventing the wheel, we’ve teamed up with the “best-of-breed” providers from around the world to bring together their infrastructure and management coupled with our technology, ideas and engineering designed by Chartered Engineers and Chartered IT Professionals. We’re an “enabler”, often working behind the scenes as an engineering or managed interconnect partner for other operators.

Our entire network is based on a private cloud which allows us to scale our resources up and down whenever required. This “balloon” type of architecture makes us one of the most flexible, scalable, resilient and powerful networks in the world. We’ve spent years researching, planning and testing our services using sound engineering principles, good management and good customer services, and in doing so we’ve been successful and gained a reputation for operating a quality, resilient and redundant infrastructure.

There are many competitors who offer similar services, but many are just resellers or sometimes even resellers of other resellers who ultimately do not control or operate their own network, or have low-level SS7 connectivity and peer at the most important internet exchange points. Without this, it would be much harder to give customers both high reliability and low-level network features.

Our network is designed with a number of open-source and proprietary systems, all built in-house and interconnected with over 1,200 carriers in 200+ countries worldwide.

Information Governance (IG)

Telecoms Cloud operates a set of multi-disciplinary structures, policies, procedures, processes and controls implemented to manage information at an enterprise level, supporting our immediate and future regulatory, legal, risk, environmental and operational requirements.

All customer data is kept in secure ISO 9001, ISO 14001, ISO 27001, OHSAS 18001, and PCI/DSS compliant Data Centres within the customer’s chosen region, complying fully with local acts in various jurisdictions. All customer content and data is encrypted on reception and no staff nor company directors have access to customers’ data. A full list of our company directors is available on our Telecoms Cloud Board of Directors page. A full list of directors’ register of interests is available at our office for inspection by appointment only.

Maintenance and Operations

As a company policy we’ve decided to engage in preventative maintenance to avoid downtime for customers instead of waiting for something to break – this, combined with our 99.999% service level agreement with our customers makes us one of the best scalable, resilient, redundant and specialist communications networks in the world.

Research, Development and the Community

Interestingly, during off-peak and idle times, The Telecoms Cloud works in partnership with The World Community Grid to donate spare computing cycles to provide scientists with critical information that accelerates the pace of research into treatment and cures for Cancer, AIDS and Muscular Dystrophy, and the Fight Against Malaria. Find out more by reading our CSR policy.

We are also experimenting with renewable technology after our owners created the UK first carbon-neutral data centre in 2001. We’ve installed solar PVs at one of our sites and installed a large battery bank to store excess energy, while reducing loads using powerful virtualisation techniques by using our algorithm to calculate peak loads/times and reduce our resources accordingly.

Customers who use Telecoms Cloud can take comfort from the fact that with natural economies of scale (with cloud computing) coupled with our green measures, the telephony carbon footprint of Telecoms Cloud is one of the lowest in the industry.

Telecoms Cloud operate in the United Kingdom both as a Ofcom licensed Public Electronic Communications Provider and Public Public Electronic Communications Network. Telecoms Cloud is a member of LINX, RIPE and LoNAP and operates an extensively peered network. Our expertise spans across IP, SS7, x25 and TDM.

Internationally, where possible, Telecoms Cloud owns the network infrastructure, licenses and number ranges, allowing us full control over every call. In countries in which Telecoms Cloud does not have its own numbers, it has long-term agreements with local Tier 1 carriers. Telecoms Cloud only provides services in countries with stable regulatory frameworks, ensuring accountability and maximum uptime.

In the United Kingdom we have thousands of lines using Local Loop Unbundling (LLU) across 770 geographically separated sites (Every UK Digital Local Exchange (DLE)) fed directly from 559 Marconi System X’s and 211 Ericsson AXE10’s Telco carrier grade switches) and servers located in every major telephone exchange around the United Kingdom.

This ultimately means that our infrastructure is close to our customers, at their local exchange whilst having complete resilience with our distributed infrastructure that is spread around the country, taking advantage of BT’s huge fibre network as our backbone whilst offering a service that is local to our customers, using local phone numbers.

As call routing is controlled by the national trunk exchanges, if a DLE were to fail we can simply fail over to another exchange. This approach spreads our risk and increases our resilience, redundancy and reliability without concentrating a significant part of our infrastructure at a few locations – unlike many of our competitors who have their infrastructure in shared co-location facilities in major cities and suffer from power shortages, congestion and high running costs, as well as being at high risk from civil disturbances, radiological events, chemical weapons and terrorist attacks.

Internationally, Telecoms Cloud collects traffic from the local PSTN networks in the individual countries on the Telecoms Cloud network footprint. In these countries, Telecoms Cloud interconnects directly with one or more local network operator(s) who host our switching and routing equipment, creating a fully meshed telecommunications cloud. All critical systems on the Telecoms Cloud network are configured in geo-redundant active/standby pairs for immediate and stateful failover in case of failure.

Telecoms Cloud has built one of the biggest and best fax platforms in the world. Since 1997, we have been continually improving and adding to the power of our fax services to continuously offer cutting-edge and market leading features to our customers – creating new innovation in a legacy technology.

Our expertise spans over 20 years operating a large redundant and scalable fax platform, used by many national and international organisations. Customers use the Telecoms Cloud for a wide range of services, from inbound fax services that are then sent onwards by email, Secure Fax services that digitally encrypt faxes for viewing on a 256-Bit encrypted portal, to outbound faxing for transactional sending of faxes to multiple destinations, worldwide.

This means that our network has to be both resilient and redundant while having the scalability to scale to a customer’s requirements as and when they need it.  To achieve this, fax operates as an overlay on our voice network, offering both T.38 functionality and traditional TDM/ISDN technologies, giving customers who need the choice access to different networks as they see fit.

Telecoms Cloud operate a highly reliable and technically robust mobile messaging delivery infrastructure, interconnecting into 1,100 different mobile network operators in over 200+ countries to deliver enterprise mobile communications services. This network, combined with local country connections, ensures reliable delivery and low latency and at competitive rates for our customers.

As a Public Electronic Communications Network we operate a network that includes SS7 STPs and link nationally and internationally with other operators.  Telecoms Cloud is also a holder of mobile numbering in the UK and selected international locations to ensure we have control of the entire value chain for our customers.

Telecoms Cloud is a member of LINX, RIPE and LoNAP, and operates an extensively peered network. Our expertise spans across IP, SS7, x25 and TDM.

We have a high-performance and redundant IP network, with a core consisting of two geographically separated Cisco 7609 routers with dual SUP720-3BXL supervisory engines and distributed forwarding throughout providing 40Gbps and 48mpps per 48 port 10/100/1000 Ethernet card.

This is backed up by a total upstream connectivity of over 10Gbps provided by six different Tier 1 providers (Level3, Deutsche Telekom, Interoute, PCCW-BTN, Telia and Tiscali) and a further 6Gbps of connectivity to LINX, LoNAP, SFINX, DEC-IX & AMS-IX.

Our cloud is spread across the world and contained in multiple secure ISO 27001 data centres with accredited redundancy and resilience with an SLA-backed reliability guarantee. We hold PCI/DSS Compliance and we are able to certify to level IL2 and IL3 (HMG IA Standard No. 1 – Technical Risk Assessment) for services such as G-Cloud and we are certified to the ISO 9001:2008 standard of quality management.


Our DNS service provides a way to geographically direct users to the closest server. We’ve built a global server network, with DNS servers geographically distributed across the world.

We’re continually expanding our DNS network to be closer to our customers. A number of ISPs deliberately route DNS traffic to the nearest DNS server to speed up response time. This only works if your provider has servers around the world; we of course do.

Our global network of DNS servers has been carefully built to maximize uptime and reliability. Each production server is fully independent of the others to avoid the possibility of a cascading failure. We run our servers substantially below maximum capacity to leave plenty of room for both expansion and unplanned large traffic increases.


Our Email Service is a highly scalable and cost-effective bulk and transactional email-sending system.

For high email deliverability, we use content filtering technologies to scan outgoing email messages to help ensure that the content meets ISP standards. The email message is then either queued for sending or routed back to us for corrective action. We have a built-in feedback loop, which includes notifications of bounce-backs, failed and successful delivery attempts, and spam complaints (should any arise).

Our emails are sent using DKIM. DomainKeys Identified Mail (DKIM) lets Telecoms Cloud take responsibility for an email message that is in transit. Technically, DKIM provides a method for validating a domain name identity that is associated with a message through cryptographic authentication. This industry-standard method, which is accepted by most ISPs, aligns our email reputation with our domain reputation. This ultimately helps to ensure that when we send you an email, it is actually from us and not a fraudster or impersonator.
