After our administrator quit, we started looking for an external one for our server. The Black Rack company has been recommended to us. After a single conversation regarding the scope of activities, we started to work together. Initially, we had concerns about the process of online store migration to a new server. Fortunately, they were unfounded, because the entire migration went very well. The website was not available for a very short time and all the work was carried out in the evening hours and was successfully completed. What is more, BlackRack suggested a few improvements that solved the problem with slow page loading!
