Yes, that seems to be the case, however the problem is that Movistar is not doing anything for now and some of the answers it gives to people’s complaints are that “the problem is Cloudflare’s”

I am sorry to hear this. It sounds frustrating!
I’ve seen topics even with few other different ISPs here acting in such way.
If Movistar is attributing the issue to Cloudflare without taking immediate action, that can definitely leave users feeling stuck.
The reality is, Cloudflare provides services for many websites, acting as a proxy between users and web servers.
Movistar placing the blame on Cloudflare, it may mean they’re having trouble troubleshooting the actual cause, or feel it’s out of their control, but that doesn’t mean there’s nothing they can do on their end to help resolve it at least :man_shrugging:
Wonder if escalating this to Movistar would help, if it’s not already as some companies respond more quickly to issues raised publicly.

It’s still ongoing:
As seen here:

( direct link to RIPE Atlas - RIPE Network Coordination Centre ) where you can see the results and see that some ASN (Movistar, Digi) are blocking some IPs from the Cloudflare Network. This is impacting not only us but also lots of other clients.

Even if we have already opened tickets with Movistar to provide as much awareness about this, please, someone at CloudFlate talk to Movistar to solve this issue as fast as possible. We may be forced to switch Cloudflare for other providers, as we have a proportion of clients under Movistar, and we cannot ignore this issue.
