Hey there @nickroz1 Thank you for your patience while we investigated this issue! We want to provide you with a complete understanding of our investigation thus far.
On May 5th, some Internet Service Providers (ISPs), specifically Comcast Business and Optimum (Altice USA/Cablevision), incorrectly flagged retool-edge.com as a phishing domain and began blocking it at the network level around 6 PM UTC. The domain retool-edge.com is the Content Delivery Network (CDN) that Retool uses to deliver front-end assets such as JavaScript and CSS. When this domain is blocked, applications fail to load completely, resulting in a white screen or an infinite loading spinner.
This was a false positive by those ISPs, and we want to assure you that Retool's infrastructure has not been compromised. We have submitted removal requests directly to the affected ISPs and are actively working to lift the block.
Workaround:
While we work toward a permanent resolution, switching to a public DNS resolver can bypass the ISP-level block and restore access immediately. You can find full instructions on our status page.
Quick Instructions:
- Mac: Go to System Settings → Network → Select your connection → Details → DNS tab → Add
1.1.1.1→ Click OK. - Windows 11: Go to Settings → Network & Internet → Select your connection → DNS server assignment → Edit → Manual → IPv4 → Add
1.1.1.1→ Click Save.
If your devices are managed by your IT team, they will need to implement this change. Alternatively, switching to a hotspot (a non-Comcast/Optimum network) is also a quick test.
We will update the status page as soon as the ISP blocks are resolved, so please subscribe (Retool Status - Front-end assets from retool-edge.com failing to load for some customers) to get the latest. We apologize for any disruption this may have caused.
