There are 3 types of checks we perform continously:
1. Http response check. We're checking your website response header - our system simply checks if your website is responding and it doesn't return any error code. We do it every 5 minutes. It's a simple and fast check. We don't log results if response is correct.
2. Website loading time check. We are accessing your website just like normal user does. We log how much time does it take to display your website in real browser. We visit your website every 15 minutes and response time is logged. We use this chcecks for statistics, which you can access in user panel.
3. Website content check. We get html code of your website and compare it with our local copy of your website. We make this checks every hour and we don't log if everything is ok. This checks are used to detect unauthorized changes in your website code.
So in every 24 hours we do ~288 response checks, ~96 loading time checks and ~24 content checks. That's ~ 408 checks total, but don't worry - only ~120 are like normal yser visits, so it has no impact on your server.
If you change your website url it's a good practise to leave redirect from your previous url to the new one. If you did so our system will detect redirect and create incident and you will be notified. Then all you need to do is to click, that you confirm, that this is your new url.
If you don't want to create redirect for some reason, you just need to login to yojr account and change url in user settings tab.
Incident is an unwanted event, which happens to your website. When our system detects unwanted event, we start incident. Starting incident means that you get notified, abt what happened and we keep checking your website every minute, until event is fixed.
The most common type of incident happens when your website is offline. Another ones are related to wrong https response codes. Changes detected in your website content start another one type of incident. The last type indicates that spam (unwanted) keywords are detected in your website content.
We will give you a detailed informations of what happend and what to do. You should contact your server administrator and provide him this informations.
If you are administrator of your website and it was hacked, you should changebyour server password, upload backup to your server, wait few minutes and check if our system detects the changes. If backup was restored incident should be closed by our system and you will receive message, that everything is fine back again.
If you don't have backup of your website, you should check your code very carefully and manually remove all suspicious parts of it. On incident details in user oanel you will see exactly which part of your code has changed. This should help. If you will remove suspicious code you should receive message from our system, that everything is fine back again. And - of course - you should start making fresh backup, now you've learned your lesson :)
