I've published some thoughts on the problems with the network tiering system: tier1-analysis.53bits.co.uk This includes a report comparing the Tier 1 networks and largest non-Tier 1 networks for Q4-2025: tier1-analysis.53bits.co.uk/part3/2025/R...

#DENOG17 is Monday and Tuesday next week, you can buy a free ticket to watch remotely (onsite is sold out). It's all in English and there should be something for everyone www.denog.de/de/meetings/...

For November's NetLdn we have no presentations, but don't worry, it's intentional! Instead we are having an end-of-year party co-hosted with our friends at @lonap.bsky.social Come join us from 1830hrs on our regular 2nd Thursday of the month (13th Nov), to celebrate the year that's just flown by.

My talk "Rewriting BGP Origin" from #RIPE91 is now online - some networks manipulate routing information and it's time we talked about it ripe91.ripe.net/programme/me...

It's actually not true

I'll be at #RIPE91 - If you're also going, come and say hi!

Good news, we've found a new home and will be back on 12th June, in "Henry's Den" downstairs at Finch's, Finsbury Square; a short walk from Moorgate, Old Street & Liverpool St maps.app.goo.gl/9wDtEW18MZqY...

We're on hiatus whilst we look for a new pub. If you're working on something you'd like to talk about when we return, please let us know: netldn.uk/cfp/

I agree with the overall sentiment of the piece but there are some not very representative assumptions in there.

I wonder how many 6500s/7600s are still out there, which have a theoretical limit of 1024k prefixes in TCAM, and are about to explode? :D

I'm now reading this, a must read for making use of one of Rust's most powerful features, thank you @mara.bsky.social !
