After touching base with our 3rd party CDN provider, MaxCDN, we have received word that they are having issues creating new CDNs for accounts. You will see the effects of this if you are in your User Portal, my.wpengine.com, attempting to activate your CDN.
Your patience is appreciated with this matter, and if you have a CDN ticket in with us, there will be a wait on us activating your CDN internally as well.
Please note that this will not affect currently active CDNs, and we will update you as soon as we have been notified that they have resolved this issue.
Update: 7:34 PM Central: We have received confirmation from our 3rd Party CDN Provider that the issue has been resolved, and we have confirmed that “Zone Provisioning” is working again.
