According to the official site, SimpleHost does not operate their own data center, and instead, they have been cooperating with DataCenter101 for a data center in Columbus, OH. In terms of the network, the only piece of information is that the infrastructure is powered by Cisco equipment. No more details could be found.
The bad news is that SimpleHost has frequent network issues periodically. For example, in November 2015, there was a network outage lasting about 4 hours and two other network issues one of which was resolved 4 days after it was founded.
Our expert monitoring tells that SimpleHost performed well in speed in December. Below are the recent stats of the server response time.
