our clients say

Fay Carter

"Throughout the delivery of our new data centre on365 has proven to be an excellent source of knowledge and support to us.  Throughout the life of our project the on365 team dedicated themselves to ensuring that the best possible solution was designed and delivered within very aggressive timescales and to an excellent standard. Should the opportunity arise again I would thoroughly recommend working with the on365 team again. "

Keith Bell

"Great Job done by your Team as usual. Surprised most people here how quickly it was done, mainly down to the planning and prework by yourselves"

John Dilkes, 
Network & Security Infrastructure Manager, Harrods

"on365 designed, delivered and managed the whole process of our new Datacentre build. We were able to continue operations while the store was open, even throughout the Christmas abd Sales periods. It all went very smoothly and the only thing that some customers may have noticed was the presence of a crane outside the building. With the help of on365, the whole installation took place with an absolute minimum of inconvenience to our customers and without upsetting local residents"

Mark Brackley
, MIS Director, Kingston Technology

"Having recommended InfraStruXure, on365 also provided cabling services, electricians for the three-phase feed into the room, as well as configuring the solution, the environmental monitoring and training for datacentre staff. Their professional approach and planning throughout the build-out meant they continuously showed up other contractors on the site."

Ian Tinsley, 
Information Systems Manager, Accord Housing Association

"We are over the moon with the system it is performing extremely well and has already covered us for a couple of power outages. Pass on my thanks to the team, they did a great job, I was very happy with the service received"

Miriam Buckley, Biomni
"I have just come off the phone with my client and they are very pleased with the new UPS unit. They have asked me to thank you for the professional way the whole process was carried out from the difficult un-loading situation to the final switch on. They were nervous about things being switched on and off, but you were able to answer their questions and help them get over it."

Martin Hinchcliff, The Derbyshire
"Congratulations on achieving your APC Gold Partner status. It’s nice to be recognized in the industry. We will always support our on365 contract. It’s vital to our business. Well done to all your team and thanks for your support over the years."

Stuart Brameld

"Many thanks for your help over the last few months. The new power supply to our racks is in and working along with the new PDUs and UPSs you supplied and spec’d. Your help and advice was much appreciated, particularly liasing with our electrician to ensure we had the right solution. I realise we also made some last minute purchasing decisions which required you to get kit out the door pretty quickly, so thanks for Yvonne and Nicola for their help in ensuring speedy processing and delivery."

John OShea
, VP Technical Strategy

"I would just like to express my appreciation for the sterling job that the team did over the weekend. We have had quite a few external contractors in doing work for us over the years, and I wish more of them were as good and conscientious as those two. Thanks again for making this a very painless process for us."

Phil Knowles

"Just a quick note to say thanks for sorting out the APC issue as quickly as you did. Many thanks. Can you also pass on my thanks to your install team? They did a great job, very friendly and professional."

Allan Fitzwater

"on365 were asked to try and solve a problem where no solution seemed possible. We had critical IT services running on overloaded and problematic UPS systems and needed to improve our sites reliability having had two total Data Centre blackouts in the space of a couple of months.  By carrying out a detailed audit of our building power systems they were able to identify a suitable spare power feed and put forward a proposal to install a new UPS, bypass panel and distribution system in our ageing Data Centre, negotiating multiple obstacles and obstructions along the cable route.

Lee Archard
, Hosting Implementations Manager, Telstra Europe Ltd

Meenu Advani, Systems Administrator, Cellzone

"A short note to say thank you for a job well done. Yvonne McDonald, who is an absolute angel, has taken all my calls and answered all my questions patiently. The two Engineers who came in to do the installation were great to have around. They knew what they were doing and got on with the job. Last but not least, a very neat and tidy job, they cleared up and didn’t leave a mess. Fantastic"
