Prize Picks - gelocation/vpn/fraud system
by Justin Krejci 11 Sep '23

11 Sep '23

Yes, unfortunate geolocation/vpn troubles strike again. If any from PrizePicks.com are on here I would appreciate if you would reach out to me regarding a mutual customer not able to use your services. If anyone else on NANOG has a contact there, I would appreciate some help getting in contact to resolve an issue that the regular support channel is unable to do. Thanks! Justin Krejci

Captive portal for suspended accounts
by Steve Saner 11 Sep '23

11 Sep '23

We are a combination fiber and fixed wireless ISP with around 20k subscribers. Management is wanting to develop something along the lines of a captive portal for suspended accounts such that those customers are forced to a portal that allows them to make payment and get reactivated. This is a common thing for a cafe wifi hotspot or something, but has anyone here attempted to do it at this kind of scale who would be willing to share their experiences? If someone has successfully done this, I would love to pick your brain a bit to understand how you accomplished it. Thanks much. -- *Steve Saner* | Senior Network Engineer ideatek INTERNET FREEDOM™ FOR ALL 316-640-8715 ext. 4005 | 111 Old Mill St., Buhler KS,67522 | <http://ideatek.com/>ideatek.com This email transmission and any documents, files or previous email messages attached to it may contain confidential information.

Lossy cogent p2p experiences?
by David Hubbard 11 Sep '23

11 Sep '23

Hi all, curious if anyone who has used Cogent as a point to point provider has gone through packet loss issues with them and were able to successfully resolve? I’ve got a non-rate-limited 10gig circuit between two geographic locations that have about 52ms of latency. Mine is set up to support both jumbo frames and vlan tagging. I do know Cogent packetizes these circuits, so they’re not like waves, and that the expected single session TCP performance may be limited to a few gbit/sec, but I should otherwise be able to fully utilize the circuit given enough flows. Circuit went live earlier this year, had zero issues with it. Testing with common tools like iperf would allow several gbit/sec of TCP traffic using single flows, even without an optimized TCP stack. Using parallel flows or UDP we could easily get close to wire speed. Starting about ten weeks ago we had a significant slowdown, to even complete failure, of bursty data replication tasks between equipment that was using this circuit. Rounds of testing demonstrate that new flows often experience significant initial packet loss of several thousand packets, and will then have ongoing lesser packet loss every five to ten seconds after that. There are times we can’t do better than 50 Mbit/sec, but it’s rare to achieve gigabit most of the time unless we do a bunch of streams with a lot of tuning. UDP we also see the loss, but can still push many gigabits through with one sender, or wire speed with several nodes. For equipment which doesn’t use a tunable TCP stack, such as storage arrays or vmware, the retransmits completely ruin performance or may result in ongoing failure we can’t overcome. Cogent support has been about as bad as you can get. Everything is great, clean your fiber, iperf isn’t a good test, install a physical loop oh wait we don’t want that so go pull it back off, new updates come at three to seven day intervals, etc. If the performance had never been good to begin with I’d have just attributed this to their circuits, but since it worked until late June, I know something has changed. I’m hoping someone else has run into this and maybe knows of some hints I could give them to investigate. To me it sounds like there’s a rate limiter / policer defined somewhere in the circuit, or an overloaded interface/device we’re forced to traverse, but they assure me this is not the case and claim to have destroyed and rebuilt the logical circuit. Thanks!

In response to feedback from operational security communities, CAIDA's source address validation measurement project (https://spoofer.caida.org) is automatically generating monthly reports of ASes originating prefixes in BGP for systems from which we received packets with a spoofed source address. We are publishing these reports to network and security operations lists in order to ensure this information reaches operational contacts in these ASes. This report summarises tests conducted within usa, can.

EDU zone operational announcement: DNSSEC algorithm rollover
by Wessels, Duane 05 Sep '23

05 Sep '23

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Verisign will soon begin the transition to DNSSEC algorithm 13 (ECDSA) for the EDU zone. Over the next few days, algorithm 13 signatures will start to appear in the zone, followed by the algorithm 13 DNSKEY records. We expect the DS record for the EDU zone to change from algorithm 8 to algorithm 13 between September 12-15. Additional information can be found at our blog post and DNS-OARC presentation URLs below: https://blog.verisign.com/security/dnssec-algorithm-update/ https://indico.dns-oarc.net/event/47/contributions/1012/ We expect no operational impacts for end users, but please feel free to reach out to us with concerns or any observations of anomalous behavior related to this algorithm rollover.
