I invested in 20i about 4 years ago and moved all my websites there - a mix of php / wordpress and .net / windows

They should not be advertising .net / windows hosting. I have a total of 17 support tickets regarding their windows hosting, The last ticket has been open for nearly a year.

They have continually and constantly provided the worst windows hosting in my 20 years of developing. The .net website randomly goes down for hours on end with 503 errors. There is nothing I can do but rely on support ( it is and has been down as I write this for 7hours. )

There are no logs provided, restarting the app pool used to work, but not anymore. Each tech support engineer goes down a different path. The last engineer suggested a redirect issue in the .htaccess file.... its a .net website. it doesn't use the .htaccess file. suddenly, it will return online and the engineer will claim "a temporary issue with the database server" - or similar. The website ran perfectly on the previous host.

Their wordpress / php hosting has been fine. but should it have any problems I don't hold any hope for their support staff to be able to sort it.

I have lost clients because of hosting with 20i... so if you're looking for reliability, be warned.
