What is the issue you’re encountering

CF Website Down page shows up randomly briefly and site is not down. If I go to another page on the site and then back to the first page, the site page appears. This happens in a matter of a few seconds. It happens randomly. We just got over a bot attack and we were using CF on DDoS attack for a period of time, or on highest security. That attack is passed now. Anyone have an idea on why this is happening?

Thanks, we did download those tips and sent it to server people. They are looking into it. The CF site down page shows just briefly, randomly. If we recycle the page or go to another page on the site it works. Server Point said the issues the tips pointed out usually last more than a few seconds. They are checking. Thanks
