Not surprising, since I am an utterly awful typist. The link I gave in my post provides enough redundant context to work out the correct answer in this case: https://infragard-boston.org/ The gentleman's name is Robert ("Bob") Antia. Unrelated to that small faux pas on my part, I also would just like to mention that I have only just now been pointed at an additional relevant online document that provides more clarity as regards to who, or what, ended up owning the original Athenix's intangible assets following its demise. https://patents.google.com/patent/US5119494 In the case of this patent, ownership seem to have untimately been assigned to: JACKSON, DAVID HOOK PARTNERS II C/O DAVID J.

Reflection DDoS last week (was: syn flood attacks from NL-based netblocks)
by Töma Gavrichenkov 28 Aug '19

Peace, Here's to confirm that the pattern reported before in NANOG was indeed a reflection DDoS attack. On Sunday, it also hit our customer, here's the report: https://www.prnewswire.com/news-releases/root-cause-analysis-and-incident-r… tl;dr: basically that was a rather massive reflected SYN/ACK carpet bombing against several datacenter prefixes (no particular target was identified). -- Töma On Sat, Aug 17, 2019, 1:06 AM Jim Shankland <nanog(a)shankland.org> wrote: > Greetings, > > I'm seeing slow-motion (a few per second, per IP/port pair) syn flood > attacks ostensibly originating from 3 NL-based IP blocks: 88.208.0.0/18 > , 5.11.80.0/21, and 78.140.128.0/18 ("ostensibly" because ... syn flood, > and BCP 38 not yet fully adopted). > > Why is this syn flood different from all other syn floods?

Looking for a Google contact (peering frustrations)
by Jon Sands 28 Aug '19

28 Aug '19

AS397031 here, located in Telehouse (7 Teleport). We picked up a port on NYIIX specifically to peer with google and cloudflare. We were doing around 6gbps inbound from google over the NYIIX for some time then without warning google withdrew routes from us, I'm guessing because too much bandwidth over an IIX and they prefer a private interconnect at that point. So we requested to peer with them via a PNI and were denied, saying they can't do that either as they're not located in any Telehouse buildings. So I'm left with no Google peering A 10gb wave from where we are to the nearest google peering point is basically the same cost as 10gbps from HE, so trying to figure out my best options here. Open to suggestions! Ideally we would love to peer with google again over NYIIX if possible. -- Jon Sands MFI Labs https://fohdeesha.com/

Facebook launches alerts for local first responders
by Sean Donelan 27 Aug '19

27 Aug '19

Facebook announced its new Local Alerts feature. Potential uses include storm warnings and advisories for extreme temperatures, evacuations, road closures, active shooter situations, bomb threats, missing person reports, water main breaks and more. The aim is to keep its users “safe and in-the-know.” https://www.washingtonpost.com/weather/2019/08/27/facebook-launching-local-… The Facebook Local Alerts appears to be a closed, walled-garden system, requiring local emergency managers to setup and maintain Facebook accounts. Emergency managers have used multiple social media platforms for several years, but its always a bit hit&miss reaching the public using different platforms. Smart assistants like Alexia, Google Assistant, Apple Siri or streaming services like Netflix and Hulu don't don't proactively provide local emergency alerts like Cable, TV and radio broadcasters. If you need to ask Alexa if there is a tornado warning, you probably already know there is a tornado.

IP Route Hijacking Bad Actor: AS57129/RU-SERVERSGET-KRSK, RU/Optibit LLC

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Howdy, I'm soliciting any background information, anecdotes, shared experiences, previous evidence, etc. of bad behavior and/or IP route hijacking for this 'hijack factory', as I've heard it called privately. They are actively -- and illegitimately -- announcing prefixes which are (legitimately) allocated to other organizations, a couple of them are very large & well-known U.S. healthcare providers. I'd also be interesting in hearing suggestion on the course of action one of these organizations might take to make this stop....

SLA language about monitoring route leaks and inter-connection issues
by Sean Donelan 26 Aug '19

26 Aug '19

Do any major ISPs have SLA language about monitoring inter-provider agreements for route hijacking, route leaks, address spoofing, and so on? I'm looking for something more proactive than waiting for a customer to notice a problem and open a trouble ticket.

DNS cache hold of SERVFAIL responses
by Stephen Satchell 26 Aug '19

26 Aug '19

This is for any Google admin on this list: When you receive a SERVFAIL from a name server listed as authoritative for a given domain, how long is that negative look-up cached? When you receive a SERVFAIL from the root servers, how long is that negative lookup cached? Does Google follow RFC 2308? Is there a common cache for all resolvers, or do each resolver in your DNS server corps maintain a local cache? When a SOA (when you see one) says 14400 for the minimum TTL (or negative cache TTL) does Google honor that hold time?
