Oh don't worry about the MikroTik's, they just do that (reboot unexpectedly in production at inopportune times)

Depending on your network set up, for connecting to bgp.tools until maybe a couple of hours ago the (non reasonable, but real) answer may have been up to 22!

It turns out on IPv4 bgp.tools has been advertising the wrong TCP window scale for quite some time and it's a true testament to TCP's flexibility that any of this was working in the first place.

Regardless, connection setups on bgp.tools should now work a little better on IPv4 now that your machine wont have to send 21 extra packets

Here I was waiting for output on a tcpdump -ni any host 3306... that should have been port 3306, but of course in the world of inet_aton "3306" is a valid IP address of 0.0.12.234!

Thanks inet_aton!

A) Cogent is now averaging at 800 tbit/s of traffic

B) While their office broadband biz is 4%~ of their total traffic, it's 43% of their $ revenue! Not bad!

C) For their off-net IP offering (aka, they use another provider to do the last mile) over half of the cost to the customer is to the last mile loop provider!

Attachment: Today, we're about 46% of our addresses are leased and approximately 4% of our addresses are allocated to customers at no cost. This is nothing new. It's been part of our strategy to win business since Cogent's inception. But we do still have half of our address space that is sitting fallow. We have greatly improved the marketability of that address space by being able to deploy RPKI or additional security features across those addresses, which have made them more desirable to counterparties.]]> https://benjojo.co.uk/u/benjojo/h/yYzKbPLt411kk7jw9q Mon, 06 Apr 2026 22:38:19 UTC https://benjojo.co.uk/u/benjojo/h/yYzKbPLt411kk7jw9q It's a outrage that Firefox only has these two adorable error icons for the mascot so far: https://github.com/mozilla-firefox/firefox/tree/4cbe9648c5d4c1cf600b7a8c3589e4589541ded5/toolkit/themes/shared/illustrations
