What could possibly go wrong with setting an example like this?
Cogent Communications will pull the plug on its connectivity to customers in Russia in response to President Putin’s invasion of Ukraine.
The US-based biz is one of the planet’s largest internet backbones – the freeways of the internet – and says it carries roughly a quarter of global ‘net traffic.
Modern-day “aggregators”, of which Cogent is one, often are the source of address delegations as well. Cogent has confirmed they’re canceling IP addresses delegated out; when you are using an aggregator you don’t actually “own” any delegations you may have as for routing purposes the aggregator has the registration on those. For residential users this is not a major issue, but for commercial places where reverse mapping is a factor it can be at least a moderate hassle.
