A few days ago I started getting complaints from users that they were having problems getting into American Express website. The homepage would load, or partially load and the login page would only ever partially load. Upon getting access to a users machine, I was able to see the requests that were failing in the dev console. All of the failing requests were for assets like javascript, css, images, etc. and were to an Akamai domain.
As a last resort, I tried reaching out to Akamai to see what was going on. They responded that the ip address that was being observed (155.190.7.19). It looks like from checking a couple of ip reputation websites that this IP is detected as a proxy which might hurt reputation.
Is there a way to get Umbrella to not change the users IP address for certain domains? I tried adding both the Amex site as well as edgesuite Akamai domain to the Umbrella policy destination whitelists as well as the destination whitelists and domain management > external domains but despite that, the websites were still not loading.
