Is there anybody on this list who keeps firewall logs and who
DOESN'T have numerous hits recorded therein from one or more
of the following IP addresses?

This is an automated weekly mailing describing the state of the Internet
Routing Table as seen from APNIC's router in Japan.

If you aren't aware of the Supply Chain Notice of Proposed Rulemaking, you

The Federal Communications Commission has put the presentations from the
Webinar earlier this week on Network Resiliency for Small and Rural
Communication Providers up on its website.
Federal Communications Commissioner Geoffrey Starks is holding a workshop
next week, June 27, 2019, to hear from interested parties on how to
address the national security threats posed by insecure equipment
within our communications networks.
This.
I've had some timing issues ( unrelated to NTP ) with certain combinations
of FlightAware RTLSDR USB sticks and Pi models. IIRC USB and Ethernet share
the same bus on the Pis, and that can cause bumps.
GPIOs run right off the SOC, avoiding that.

I readily admit that this device isn't large enough for most cases, but you can
get cheap and small MPLS routers.
I still have SIP connections to the Globalinx system to IPs that are in 17184.
I don't believe this part was migrated yet because whenever I call in for
support issues, no one has any idea how to find the configured accounts.

Well yes

We'd typically do this for very high-speed ports (100Gbps), as
hey,
So what is the primary goal of us using the aggregation/access layer? It's to
achieve better utilization of the expensive router ports right? (hence called
aggregation)
I'm in the eyeball business so saving router ports is not a primary concern.
Aggregation exists to aggregate

With automation we break far far less often, far far more. MTTR is
also increased due to skill rot, in CLI jockey network you
