This is the first time we use our blog to post our experience with one of our ex-vendors that we used to outsource cloud hosting management services. Specifically, this article is about our bad experience with OnApp. I will include as much details as possible in order to be as helpful as possible to any future companies considering to use their services. I want to stress out that I would not write this long OnApp review but the way they treated us made me do it because in todays world such behavior must result in lost customers and lost future clients. Everyone should be aware what to expect by becoming a customer of OnApp. I will explain about the most serious issues because in 4 years we had to open more than 240 technical support tickets due to problems with their software which makes it 5 tickets per month and 1.25 tickets per week. In many of the cases their support staff didn’t know what they were doing and they even caused full data loss for 2 servers. Good that we had backups to restore them.
