How does that relate to the Rogers cell service outage, though? Surely SMS doesn't require BGP?

It feels like there's a big, fundamental problem affecting a variety of Rogers infra, where BGP and cell problems are just symptoms we can observe. CloudFlare says it looks more like a failure than an attack; I'm not entirely convinced.

I don’t think it’s an attack.

I’m in Canada at the moment with my UK SIM and using Rogers internet just fine. Completely unaware of any problems until my friends warned me about needing cash and I then double checked and still, phone internet via Rogers on a roaming SIM worked fine.

My guess is their voice, sms etc all are IP these days which was impacted by their BGP issues. Whereas my UK carrier roaming gives me a UK IP still, unrelated to Rogers advertised blocks.

Impacted, yes. But "no service"? That's dubious.

I hear you on foreign SIM working. I got online at a cafe just long enough to buy a Yessim eSIM. When I activated it and turned on data roaming, I had LTE working on... the Rogers network! That I didn't expect.

Nope, in contrary I will fully believe it. Circuit-switched networks are dead, period. Most "circuit-switched" networks are actually IP networks just with custom FEC'd and prioritised protocols so that there's backwards compatibility. Most Subscriber Authentication systems since UMTS and 3G CDMA (except for super-early deployments, and since they have LTE they would have migrated it if it were the case) have moved into an IP-based system because it's cheaper, and if that's down then everything is down.
