NANOG92 travel grants or sponsorships?
by Adam Thompson 16 Aug '24

16 Aug '24

Does anyone know if there are travel grants or sponsorships available for people who cannot afford the US$700 (~C$1k) registration fee and/or travel expenses, out-of-pocket? Asking for a friend *cough*... (Yes, I'm aware of the $100 Virtual option, it's not a good option for me.) -Adam Adam Thompson Consultant, Infrastructure Services MERLIN 100 - 135 Innovation Drive Winnipeg, MB R3T 6A8 (204) 977-6824 or 1-800-430-6404 (MB only) https://www.merlin.mb.ca<https://www.merlin.mb.ca/> Chat with me on Teams<https://teams.microsoft.com/l/chat/0/0?users=athompson@merlin.mb.ca>

Telstra/GTT high latency in Singapore
by Scott Q. 15 Aug '24

15 Aug '24

I know this list is only for N/A but curious if anyone might have an insight. We use IBM Cloud in Singapore and they use Telstra which connects to GTT locally in Singapore, but their local latency is wild, spanning from 2ms to 40ms. Both are solid providers so what could cause such delays for local traffic ? 1. AS36351 61.23.5177.ip4.static.sl-reverse.com (119.81.35.97) 0.0% 100 0.6 2.8 0.5 95.0 11.1 2.

Any ideas how long gmail cache DNS records ?
by Laura Smith 13 Aug '24

13 Aug '24

In typical "Google knows best" style they appear to be ignoring SOA and TTL and doing their own thing. Changed DNS severs and MX records, other public mail services have picked it up no problem. Gmail however appear to be insisting on continuing to deliver to the old mail servers for god knows how much longer ? Any ideas how long I can expect this to go on for before they Do The Right Thing (TM) ?

Unlocked ATT copper cabinet in Austin TX
by Chris Boyd 12 Aug '24

12 Aug '24

If anyone on the list knows how to get info to ATT local repair in Austin TX, specifically the Hickory CO, I’d appreciate you forwarding this info. All the repair pages want a local ATT number to report problems now, and I’m no longer an ATT customer. The copper cabinet on Monroe near Travis Heights boulevard is unlocked and open. The copper cabinet is next to a fiber node labeled XR0416. https://imgur.com/a/n8bB2tJ

Fastly Peering

I've been trying to contact Fastly for over a month to setup a bgp peering session with them, but I haven't gotten a response from three separate emails. They say they "Have a selective but generally open peering policy" If I haven't gotten any response should I just take that as a "No"? -- Elijah Zeida | AirBridge Broadband - Network Engineer Office: 208-494-4343 | Direct: 208-494-1260 https://airbridgebroadband.com | 231 W Main St, Grangeville, ID 83530

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.
