Amazing how the business support at these ISPs is about as good as warm body tier 1. You haven't heard an update from me because the last message I sent you was "hey nobody has provided a real update, we don't have a downlink, fix your shit"

6x6mbps being the minimum viable to run a retail environment in "good" condition is wild to me #networkadmin #networkengineer

The Manitoba Network Operators Group has launched a new BGP Looking Glass! Its such a big upgrade we're calling it MBNOG Looking Glass 2.0 even! I've been contacting a bunch of local networks trying to get them and their routes peered. If you run BGP locally in Manitoba and don't have a looking glass to view your own routing table I would suggest you contact me and we'll get your network peered up!!

I am a network nerd (#NetworkEngineer) focused heavily on #BGP #routing, #DNS #Anycast, and modern #WebServices. I'm very interested in #InfoSec as it is directly adjacent to, and often intertwined with the network layer.

I run my own #HobbyASN, operating AS395089 on the public internet using mainly #Mikrotik routers and switches. I #blog about my experiences at https://bgp.guru/

I love in #Winnipeg #Canada, and am involved in the local #InternetExchange / #IXP community, sitting both on the board of directors for MBIX, as well as participating in the MBIX Ops Team.

Outside of the Internet, I am also quite interested in #RetroGaming, focusing heavily on the #SNES era.

Navigate the Network: Mastering Wireshark Filters 🦈🔍

Drowning in network data? Learn how to use Wireshark filters to find exactly what you're looking for! Filters are a powerful tool for navigating vast amounts of packet data, whether you're troubleshooting network issues, analyzing protocol behavior, or hunting for security threats. We'll explore the difference between capture and display filters and show you how to zero in on the information that matters most.
