@ayubio @accuweather @vivobr Percebi isso a umas semanas, tanto na fibra quanto na internet móvel. Trocar o DNS realmente faz o site carregar.

@accuweather Are you receiving complaints from @vivobr broadband users in Brazil? They have about 8 million fixed broadband customers here, and I’ve diagnosed an issue affecting your site’s rendering capability.
The FQDN you use to serve .JS files via Akamai is awxcdn.com. This address is not resolving on Vivo’s recursive DNS servers. To investigate, I queried the root domain (without www) on the same DNS and received a normal A record response.
However, that root domain doesn’t appear in your site’s source code. I only used it to demonstrate the issue.
Either there’s a problem on Akamai’s authoritative DNS side preventing resolution specifically for the www subdomain on this major Brazilian operator (which I find very unlikely), or someone at Vivo has blocked this specific important address on their recursive DNS.
An emergency workaround would be to change the FQDN used in your frontend from awxcdn.com to something like js.awxcdn.com. I believe this would fix the problem instantly.
Could you please check internally (and especially with Akamai) whether the issue is on your side? If not, I have a meeting with Vivo tomorrow and can escalate the case to them. I’d appreciate a quick reply if you think I can help in any way.
