Reason for delayed tornado warnings in Iowa
by Sean Donelan 23 Mar '22

23 Mar '22

https://www.washingtonpost.com/weather/2022/03/06/nws-tornado-warning-disse… In a follow-up statement Monday, Buchanan said the communications delay resulted from a damaged fiber optic cable at the Weather Service’s Dallas-Fort Worth office. “The cable outage caused that office to switch from its primary, land-based communication network to a backup satellite-based network that serves every NWS field office,” she wrote. “The uptick in messages flowing to the central message handler from NWS Central Region offices due to the severe weather, combined with the performance characteristics of the satellite network in use at a co-located site, slowed down the queue of message transmissions and created a brief backlog across multiple offices.”

Pardon the netop relevant interjection... Most of you probably don't need this, but in my experience many did. DNS over TCP transport is a thing, please don't block it. kthxbye. <https://www.rfc-editor.org/info/rfc9210> John

V6 still not supported
by Daniel Karrenberg 23 Mar '22

Full match with my recollection about the cause for this sub optimal outcome. Happens to the best of us. One has to remember that at the time we did not consider it a forgone conclusion that the products of the IETF woukd be the foundation of the Net.

Telus contact re: VPN services (ESP, SSL) impacted, Vancouver -> Las Vegas
by Hugo Slabbert 23 Mar '22

23 Mar '22

Hi folks, Could someone from Telus (852) reach out, please? We're seeing a chunk of users on Telus home connections around the Vancouver, BC, area (Lower Mainland) struggling with RTT and some chunks of loss on VPN connections endpoints through gateways in Las Vegas as of ~2022-03-17. Outer path to the tunnel gateway is fine at <60 ms with low jitter and without loss. Tunneled traffic (predominantly ESP, but some users on SSL wrapped at times) shoots up to 130+ ms or above 200, with high variability and chunks of loss. Traceroutes from the users show outer traffic handing off to Zayo in Vancouver and across Akamai in Seattle before coming to us in Vegas. Users on other providers are unaffected. I'm reaching in case there are some shenanigans with ESP or SSL-wrapped traffic being futzed with somehow before being handed to us. Gateway endpoint is v4 only at 185.34.107.131, and is advertised out from 60229 to Akamai/Prolexic (32787). Hugo Slabbert Network Engineer Demonware

Hi, Blake: 1) " so it's not a chore to tell what thread you're even replying to? ": I am lost by your statement. I start each of my reply by quoting a phrase or sentence of the message that I am responding to. To be sure the original message in included, I copy the last message following what I am writing. I also prefix it with the forum message tag such as in this case "NANOG Digest, Vol 170, Issue 20 Message: 33 ". This should be enough for anyone to follow in the latest exchange, as well as tracing it back in history from the NANOG Digest, if interested. Anything more could I do to ease your efforts without beginning to create a long tail to a thread? 2) " ... a standards compliant mail client ...

VPN-enabled advance fee fraud
by Andrew G. Watters 21 Mar '22

21 Mar '22

Nutshell version: a group of criminals who appear to be in Mexico have created an entire fake law firm and deal flow in the U.S., with Photoshopped notary seals and wire instructions. They reportedly use ExpressVPN-- the owner of the IP block used by the suspects states that it leased the IP block to ExpressVPN under a Letter of Authorization. The suspects make money by causing victims to wire advance fees to Mexico as part of selling their timeshares, and possibly other transactions. My client has lost $70k or so thus far. He has received legit-looking documents, but upon even a cursory electronic inspection they are obvious forgeries. So this gang is savvy enough to steal money, but really reckless as well, which may explain why they are risking clicking on my links as well. I spoke with the lawyer who they are impersonating, and it was news to him that he is in New York City running a law firm considering that he retired in another state many years ago. So the suspects are offshore and I'm not sure what I can do. But I would still rather have their IP addresses than nothing. Can I have a recommendation on the best way to pursue user data from VPN providers such as ExpressVPN? I already sent in a notice to preserve logs for the involved ASN, and I'm headed to Federal court in the next few days to see if I have a chance to get even some of the victim's money back-- or at least an injunction shutting down the suspects' online presence. Any tips on getting VPN user data (or best practices in this type of situation) would be greatly appreciated. Best, Andrew Watters -- Andrew G.
