@Martin Da Rosa thanks for the response. It would not be possible to switch a live website to the src app. This isn’t a problem related to the SCA code. This is an issue related to NetSuite’s backend servers serving asset files. I noticed that even when the CDN is turned off, NetSuite is now using Akamai edge servers to server SCA web content. They use to serve the SCA website content from NetSuite servers.
My fear is that NetSuite is now using a WAF to is blocking / throttling requests if too many come from the same group of IP addresses, which would be the case if there was a 3rd party caching service like Cloudflare or Edgio in front of the NetSuite servers. NetSuite refused to accept a whitelist of IP addresses so we could prevent this issue from happening.
