Re: [44net] Lost Packets

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. Graphs used to show the packet flow for Network Telescope (44net): https://www.caida.org/data/realtime/telescope/?monitor=telescope_attack&… but those broke (~2019-12-11), giving less insight for debugging. --------- ARDC now has the resources to put independently hosted redundancy in place for 44net. Perhaps it would make sense to prioritise AmprGW infrastructure over distributions of funds to other organisations?

I believe it may be running locally-modified firmware."
