Re: COVID-19 vs. our Networks

The access facility and the underlying long haul are telecommunications services. The application provided using that facility may or may not be. The congestion you were experiencing was not with the telecommunications facility itself, but with the application running on it, and was as you state, outside of your network - on a CDN hosted service. Your argument is with your third party hosted service. Their argument is with their CDN.

Internet exchange points are not regulated. Interconnections between ISPs and CDNs are private agreements, and are always at risk of congestion and commercial dispute between the parties. There is a long history of this.

If you have a direct layer 2 or 3 private line to your hosted service provider's CDN, and it was not performing as per the SLA, then you need to take that up with them.

If the underlying telecommunications facility failed, and was classified as critical infrastructure, and not restored in a timely manner, then you need to take that up with the provider of that infrastructure.


I'm not trying to be difficult, but the fact remains that there is a distinction between telecommunications services, and Internet services. The fact that Internet services (and I'm not talking about any one particular DIA circuit, but the rather the global network of networks) work so well most of the time, such that people tend to start treating it as a substitute for telecommunications services is pretty impressive.

There are cost/benefit tradeoffs for using cloud hosted services and public Internet infrastructure. You save money by not operating the data centre yourself, but you pay for it in reliability. Your organization may have made that choice, but to say that because you chose to put critical applications on Internet infrastructure, other users of the Internet should take a back seat to your needs seems to be a bit of a stretch. Again, if your provider sold this to you as something that was NOT relying on public Internet, and was Layer 2/3 private managed services with dedicated bandwidth, then you need to have a conversation with them.

First of all, we use a mixture of layer 2/3 private lines and DIA circuits. You don't know our infrastructure, stop being condescending. It goes against the spirit of this mailing list.

Second, yes, the Internet is protected. Both public and private lines. I know this because we have TSP coded circuits and I spent four years at a Tier I ISP servicing TSP coded circuits

Third, the trouble we had was a third party service having congestion issues. They are hosted by the same CDN as Call of Duty. The problem was both outside of our control and our third party service's control. The chokepoint was between ISPs/IXPs and the CDN. I've seen this time and time again while working at the aforementioned ISP. Saturated links on ISP/IXP/CDN networks. This is where the TSP code comes in. In this day and age of cloud services, it is financially unfeasible for every company to have a private line to every single cloud provider. That's preposterous to even suggest.

The Internet is not a telecommunications service, according to your FCC. If you want predictability, buy WAN circuits, not Internet circuits.  If your provider is co-mingling Internet and WAN traffic (i.e. circuits with defined endpoints vs. public Internet or VPN), then you need to talk to them about their prioritization.

If you have mission critical applications, put them on mission critical infrastructure, not the public Internet.

Oh, that's right - Internet circuits are cheaper than WAN circuits
