I used it for 2 years and as a Senior Developer, I would not recommend this to anyone. They miss interpreted the word grace period once they came to know I m not going to continue first they asked to pay for the grace period ...
and then suspended the account 10 hours before ending the grace period and insisted to buy for one more month to recover the data if required.
I have used many hosting services including aws, godaddy, BlueHost, hostgator, Contabo, OVS, etc for different clients in my entire professional career but chemcloud is very opportunist.
also, their technical staff is so much incompetent that often they refuse to install some packages or install them in a way that is not useful and generates issues.
Personally, I would not recommend it to any of my clients.
