Web Application Firewall

17:12 UTC, Apr-21-2020 – Systems has reactivated the WAF. However, the rule that caused the HTTP 406 Not Acceptable errors for customers earlier today remains deactivated for the time being.

14:58 UTC, Apr-21-2020 – We have temporarily disabled the WAF due to reports from customers. Once we have reviewed them, we will update this post accordingly.

14:18 UTC, Apr-21-2020 – The Pressable systems team has deployed a Web Application Firewall (WAF) across our network. The WAF will make sites hosted on our platform more secure by blocking common attack vectors, such as SQL injection.

When the WAF is triggered, our servers will return an HTTP 406 Not Acceptable response code.

While our systems team has tested the WAF rules extensively, there is a chance that the rules may flag and block legitimate requests. In the event that this happens, please contact the Pressable Customer Success team for assistance.

Additionally, our systems team has implemented rate limiting on requests made to assets or pages that return an HTTP 404 Not Found response code. When excessive requests are made to assets or pages that return a 404 error, our servers will return an HTTP 428 Precondition Required response code.

If you have any questions or concerns about the steps we’re taking to improve the security and functionality of your sites hosted on our platform, do not hesitate to contact the Pressable Customer Success via MyPressable Control Panel or email, at help[@]

Required DNS Update

In 2019, we migrated all sites to our new server infrastructure. At that time, we announced that Pressable’s IP range would change, but that we would proxy our previous IP range to our new range until the end of March 2020.

After March 2020, domains using our previous IP range (209.15.20.*) will no longer resolve. Therefore, it is imperative for customers who have not updated DNS to do so as soon as possible.

To determine if the domains assigned to your Pressable sites are using our new IP range, please use a DNS look-up tool, such as this one.

If the IP addresses shown in that tool match at least one of the IPs assigned to your site in MyPressable Control Panel, then you are set. (See FAQ: Where can I find the new IP addresses for my site?)

If any one of the IP addresses shown consists of 209.15.20.*, you need to update it as soon as possible. (See FAQ: How do I change IP addresses?)

If you have questions, please take a look at the FAQs article in our knowledge base. For additional questions or clarifications, do not hesitate to reach out to the Pressable Customer Success team: help[@]

500 Internal Server Errors
