Correct. A particularly interesting case, since ORBS' transit provider was also a transit customer of Above.net. Said transit provider would announce their /16s, of which ORBS sat in a /24 or two of, and have their traffic blackholed.

IIRC they punched /24s via their other transit providers to partly resolve the issue.

But the rest of the story - let's not go there.

Why not? We _used_ to be an Above.net OC3 customer. Back around 2003, we ran into issues with Above.net deciding for us which parts of the internet should be accessible. We got customer complaints that certain web sites were unreachable through us, but worked fine on other internet services. I eventually got Above.net to give me a list of the several dozen /24's they were null routing.


This was particularly annoying because they had nothing setup to notify customers of these null routes or allow us to choose not to send them traffic they'd null route. To me, this seemed rather inappropriate behavior for a transit provider.
