We were using another local company in Las Vegas, and unfortunately, as nice as the guy was, he just could not permanently solve some of the intermittent problems on our network that had been occurring over two to three months time. We asked around, and we were ultimately referred to Integrita Systems.
Dimitri came out a couple hours after our initial call (a great deal faster than our previous guy would respond by the way), and he was literally able to PERMANENTLY solve our issue (our server was randomly bluescreening throughout the day) within 45 minutes of showing up. When he told me he found the problem and fixed it, I honestly didnt believe him--I figured it would happen again and I would have to call him back out.
A week later, he called to follow up and make recommendations, and it was then that I realized that we had made it through an entire week without the server going down.
We have been using Integrita Systems for over 5 years now, and we have closely followed their recommendations, and our system has been ultra-reliable for years. Of course, we have had some hardware fail, but they have always been able to respond quickly to emergency situations and get us up and running in relatively short order.
Highly recommended!
