We've been customers of Atlantech Online for 17 years and counting. Our company was able to grow and scale over the years because of their high quality data center hosting services and their top notch technical support team. We have never faced a challenge with our hosting needs that the Atlantech team hasn't been able to handle.

Atlantech was amazing! Robert and his team made the process extremely easy to switch from nextiva to MS Teams calling and they save us over $2,000 a year! It was seamless, the entire process took less a month, with zero down time. Thanks again Atlantech!

We have used Atlantech for a very long time, and their customer service is very thorough and helpful. They are able to assist with any questions/issues I may have as soon as possible. They ask questions and sometimes even follow up on tickets that may seem a bit more complicated. The technical services they provide are also consistent, where we don't run into issues around connectivity unless we are having an internet issue.

The techs were quick to respond and able to help troubleshoot via email/phone calls. The emails with photos on how to reboot the system were helpful. Tech was able to come out first thing the next morning to restore our service.
