If a website is down , the webmaster loses some money since the website is often monetized using advertising. The webmaster will usually contact the webhosting company for support. Based on their personal experience, how quickly does a webhosting company reply to support tickets?

In my case, my tickets are answered in less than 30 minutes. However, I use live chat functions and get help within 5-10 minutes
