DebugBear

We've built a FREE site speed testing tool. Check if your website meets Google's Core Web Vitals and see what you can do to make it load faster. Test your website here 🚀 debugbear.com/test/website-s…

We’re continuing to investigate the security incident. Our DNS server records were compromised through our domain registrar. We are currently unable to receive emails sent to our domain. Based on our initial investigation this attack targeted the website of a specific customer. We have not seen any indication of a compromise of our internal systems, though we will continue to investigate this.

We are aware of a security incident affecting DebugBear and are treating it as a top priority. We have engaged specialist cyber incident response support and will work with affected customers directly. We will share further updates here as appropriate.

We're impacted by an ongoing security incident. If you use our RUM product, please remove the embed code from your website.
