CAIDA/UCSD is beholden to random upstream filtering as much in 2001[1] and 2009[2] as it is now. And in-turn, AmprGW is/was beholden (2019) to an ethernet switch with customised firmware[3]... a blackbox.
I can answer this part, at least. The make and model is a juniper ex3300-48t. It is not running any customized firmware. Rather, the link drops down into a small vlan grouping with the link from UCSD, a link to the ampr gw box, and a port replicator. For whatever reason, when the ampr gw box reboots, there is a chance it takes the switch with it. usually, the switch just reboots, but sometimes it full on crashes and needs a power cycle.
It has been pretty stable recently, however.

In other news, I'm still waiting to hear back from UCSD. Keep in mind it is a holiday here, so it may be tomorrow.
