Our Story

Reliable IT Environments Limited is a group of IT environment experts offering an intelligent, independent, common-sense approach to analysing, quantifying and rectifying data centre environment problems. Reliable IT Environments Limited (RITEL) was founded by Dr. John Wood in 2001. John worked for IBM for over 20 years, and, since 1995, had been investigating and remedying both machine room environmental problems and digital printing issues for IBM in customer sites across Europe. In 2001, IBM UK decided that it no longer intended to provide full audit and environmental expertise as a service to its customers and Reliable IT Environments was formed.

John gathered a talented team who understand the intricate and complex challenges involved with maintaining a reliable data centre. Our clients are primarily financial institutions, insurance and communications companies, utilities, third party providers and large retailers. We provide them with independent, practical guidance on all aspects of the data centre environment.

About our Founder, John Wood

John Wood received his first degree (Physics) and his doctorate from the University of Bristol. While a laboratory-based Materials Scientist at IBM, John was responsible for analysing component field failures and for the design of many innovative IT components including the transducer on the world’s first touch screen monitor, the encapsulation of the first chip on flex disk file circuits, custom silicon chips, printed circuit boards, packaging and flexible circuits, disk files and monitors. Later, as a Senior Advisory Scientist, his experience of environmentally testing components led him to investigate and resolve machine room environmental problems and digital printing issues in IBM customer sites across Europe.

John has worked and taught at Cambridge, is an inventor on four patents (all assigned to IBM), and the author of more than 25 published papers covering passive display systems, corrosion, theoretical chemistry, electron physics and electron emission analysis, and vacuum systems. Known in the industry as Dr. Dust, John’s highly successful approach to problem solving is simple - establish the facts, recognise the anomalies, find the most practical solution possible - an ethos he has passed on to the team.

Our Client Confidentiality Policy

We’d love to crow about how significant our clients are, but, we also understand how important commercial discretion is to our clients. Therefore, we do not discuss or name our clients at any time, with anyone. That’s why you won’t see any of our clients’ logos on our website. If we share any of our previous experiences relating to a particular case, all identifying features are removed or anonymised.

Why choose Reliable IT Environments?

  • We Are Experienced. Our top expert has over 30 years of working in computer technologies and the data centre environment. We have a deep understanding of the science behind the technology. Our highly qualified staff understand completely the care required to work within a live data centre and each has at least 10 years data-centre experience. We’ve seen the inside of enough data centres to know what works and what doesn’t. Our recommendations are born out of experience and common sense. 
  • We offer a holistic approach. While running a data centre you will come across a great many experts. Air flow experts, BMS experts, floor component experts, IT component experts. Each can usually guarantee that their part works, but does it all work together? Our unusual mix of experience and understanding in all aspects of a data centre, from the individual IT component level to room-wide global environmental factors, gives us a unique and valuable perspective when diagnosing problems or making recommendations.
  • We are trusted and discrete.  We value our relationships with our clients. And our clients generally appreciate our discretion. We do not discuss or name our clients at any time, with anyone. When we share any of our previous experiences relating to a particular case, all identifying features are removed or anonymised. 
  • We are responsive and flexible.  Like you, we are a 24-hour business. We operate a 24-hour emergency hotline for disaster recovery. Our engagements and visits are scheduled to suit our clients’ requirements.
  • We are independent. We use our own calibrated equipment to take measurements. Sometimes we find that our results conflict with what in-house monitoring equipment is reporting, and usually, when we dig deeper, we find that is the root of the problem. We are not aligned with any component manufacturer so our analysis is truly objective.

What our Clients Say...

“The best value we have ever received from data centre spend.”
 - Chief Technical Officer, Communications.

"We needed assurance that our server environment is 'fit-for-purpose' so that our systems will continue to operate reliably into the future and maintain our agreed levels of service. Reliable IT Environments Ltd were suggested to us by our sister company because of previous work that had been carried out. Dr Wood's team provided us with just what we wanted. They understood the nature of our business: 24x7 business critical systems. They have an extensive knowledge of the environments that servers require. They have a detailed technical knowledge of the types of problem that can be encountered.  The report was extensive, thorough and detailed – but it was easy to pick out the items that need attention, and the level of significance that is attributed to each. Our queries were handled promptly and effectively. In summary, Reliable IT Environments Ltd exceeded our expectations in a number of areas so we will certainly engage them again in the future.”
  Business Manager, Utility.

“As a major fit out specialist delivering high quality comms room spaces for blue chip clients, we have to demonstrate compliance with specification in achieving the required ISO cleanliness levels in the comms environment prior to handover.

To test against the criteria and receive the required certification, we have always used RITEL’s services. RITEL is prompt to respond to our requests for site attendance. They always provide practical advice during room inspections, particularly where any improvements could be made or areas of risk may occur in achieving the desired result. The reports and paper work (following testing) is always concise and quickly forwarded.

We recently completed a 350 sq.m comms. room for a client and RITEL’s assistance and knowledge of the construction materials used in regard to particulate/contaminant risk, greatly assisted in gaining the required ISO certification for this space under challenging conditions, and was key to gaining a contractual sectional completion.” 
 - Technical Services Manager, Specialist Fit Out Company.

“I have worked with Reliable IT Environments on a number of projects and found their commitment and expertise exceptional. John has provided specialist information and consultancy services to the highest standard whilst maintaining a down to earth workman-like approach. Reliable IT Environments are my first point of call for every data centre related issue.”
 - Account Manager, Outsourced Facilities
