I am having the same problem. I use my IPad using Safari to access this site. It started last week.
This is a scam. I hope you haven't opened it or tried to use it.
Goingapp.xyz is what can be described as an iPhone browser hijacker that changes some of the settings of the device’s browser and causes unpleasant page redirects. Goingapp.xyz is likely to be disguised as a seemingly useful app or added as a built-in component to another application. Goingapp.xyz will also be responsible for the streams of popups and banners during your browsing sessions.
