I am using Fastcomet for past 4 years and i had only one issue with over CPU usage which caused my websites to go downtime sometimes. After taking with team they advised to upgrade my hosting package and i did it and now eveything seems fine to me and i'm currently hosting 5 sites without any downtime and no page issues. Here you can check out my site speed in the review written by me https://bloggersneed.com/fastcomet-review/ one thing i found in the Fastcomet hosting is their plan is quite overpriced and not suitable for websites which gets more than 10k website traffic per day. If you are having low traffic blog then you can go with Fastcomet hosting.
