Cloudflare: Sends DDoS Alerts to attacking sites.

Cloudflare now allows its customers to generate alerts that alert them when their sites are being attacked by DDoS.

In a DDoS attack, an attacker “floods” a server or Internet connection with more requests than it can handle. This request bombardment renders the service unavailable and the company (or individual) experiences downtime.

Cloudflare has always offered DDoS protection as one of its key offerings, but if a site owner or administrator was not actively using their site or using tracking tools, they did not know that their service was being attacked.

Cloudflare announced that all paid customers can now set up alerts to alert them when a site they manage is under DDoS attack.

Depending on your paid account at Cloudflare, you may receive email or PageDuty notifications.

There are also different types of DDoS that you can receive notification of – HTTPS DDoS and L3 / L4 attacks. The availability of each type of alert depends on the service you use with Cloudflare.

Unfortunately, Cloudflare does not provide a way to create a test alert to see how the alert will work with custom alert systems or SMS texts.

Create a Cloudflare DDoS alert

1.Log in to the Cloudflare control panel at

  1. At the top of the control panel, click the “Notifications” section.
  2. In the Notifications section, click the “Create” button.
  3. Select the type of DDoS alert you want. For most clients who use Cloudflare to protect a website, you will only see “HTTP DDoS Attack Alert”.
  4. When you are done, click the “Next” button.
  5. On the next screen, give the notification a name and an optional description. Then add some email addresses or other notification methods that the notification should use.
  6. When done, click the “Create” button to complete the alarm setup.

Once the alert is generated, when Cloudflare detects that your site or service is being attacked by DDoS, it will send the alert.
