I wonder how he contacted his colleague. In this case, I presume that routing to other networks were unaffected. But in the general case, with a future of everything over IP, what will network engineers use to communicate about faults?

- ojii 14y agoThere's a trend to use VoIP on cellphones too (see LTE). So in the future this will not help at all.
- JohnLBevan 14y agoIs there some way to say "ignore DNS results from this provider", such that were you to spot an issue you could block that provider's information (and anyone replicating their version of the truth) and thus find a valid path. If that were possible you wouldn't be reliant on a third party to resolve the issue to get your system working, and once your system worked, you could contact them to resolve the issues for all.
- ef4 14y agoIf someone is giving out bad DNS records, you can just choose to use a different DNS server. But in this case the problem was bad routes. You can certainly force your own routers to use fixed routes instead, but that doesn't help you unless everybody else along the path also does it. So it's not easy. There are tricks one can play -- like advertising your network as a set of smaller, more-specific networks (since routers will usually favor more-specific routes over more general ones).

- noselasd 14y agoEven with LTE/VoLTE, the voice packets are usually contained within the telco private network, that just happen to be IP based, with private interconnections to the other telcos. At some point we might see most of the VoIP being transported across the internet as well, but that'll be the far future.
- hhw 14y agoMany networks engage in a practice know as peering. If the author was the peering co-ordinator for his AS, he may have likely been previously in touch with the peering co-ordinator on Moratel's side when establishing a peering relationship, and would thus have had direct contact information to a pretty direct channel (peering co-ordinators are generally also network engineers). The direct contact information being e-mail, phone, IM, or even IRC (yes, some network engineers still use it). Although, the phone (non-VOIP) would be the only option not tied in to IP.
- jwr 14y agoIf you run a network with BGP, you always have good contact information for your peers. "Good" meaning direct telephone contact with tech people running the show on the other side of the link.
