We were looking for a vendor that could provide us with advice to help us build out our datacenter infrastructure in order to meet the needs of our growing business. Great Northern was able to do this and deliver on their promises. The team at Great Northern was very helpful in providing guidance and recommendations. They are extremely responsive and always willing to help and answer questions. There wasn't much I disliked about Great Northern. Their service is great and they are very professional and knowledgeable. They helped us understand what we needed in terms of infrastructure and then helped us plan and implement it.
