I’ve used them for probably 2 decades, getter in because of the $1/month for a year deal.
I think I’m on the top, or 2nd from the top, tier. Has unlimited disk space, but it’s not open access from the start. Every so many tens of GB you have to call to get the soft limit raised. They are trying to keep a bot from just filling the space up.
I use their hosted WordPress, so that they handle the upgrading.
I also have run a few wiki sites on there. Those install and run fine.
I wish I could figure out if I could install OwnCloud or such on there. I’m not great with Linux. You don’t have rights to the OS, but anything you access through a webpage or FTP you can put there. You should have access to chron jobs, but my skills aren’t there yet.
I mainly use them to host my own email domain, that I then access from gMail.
Biggest problem I’ve had with them is they will charge extra if you use a phased-out version of Python. So you have to make sure you keep anything using Python updated.
