As someone who did sysadmin for particle physicists in the 1990s, it was a bit of a surprise to me too.

[Brian Cox @ProfBrianCox]

As a particle physicist of 1990’s vintage it’s come as a huge shock to me today that the World’s critical IT infrastructure doesn’t all run on Unix and isn’t written in Fortran 77.

@DanJPerry @timmarshall @RestIsPolitics Well enough thanks, hope you are too, I'm sure our paths will cross again at some point!

@mike_hooz @lileeny @tstrickx @tomm3h @flangey Maybe a sesqui-trireme.

Even after vote earlier in year not even to increase fees in line with inflation. end/

[Rob Evans @internetplumber]

Each year @ripencc membership vote on redistributing surplus. Due to vote of fees earlier in year, surplus expected to be small, or slight deficit this year (between EUR +7 and -7 per member). 1/

[Rob Evans @internetplumber]

Board/CFO suggested membership voted "no" to redistribution and surplus or deficit went into or came out of reserves. Somehow membership still voted "yes" to mess about with small adjustments to next year's fees. 2/

Thread on <mailing list> discussing the pitfalls of a weekly posting of list stats (e.g. number of messages posted by each participant) has now exceeded the number of those messages sent to the list in a year...

@TeamARIN Not entirely sure the Internet has ever been "simply a massive commercial activity."

[Rob Evans @internetplumber]

@wright_s @ripencc Fair enough. I did mean to write “(conservative?)”, but either way it’s a lot of address space and more than pocket money.

[Rob Evans @internetplumber]

According the @ripencc alloclist, yesterday's IPv4 transfers into https://t.co/u7Me71JnW6 were:

5 x /16
1 x /15
1 x /14
1 x /13
1 x /12

At a (conservative) estimate of US$45 per IP address, that's US$103M of transfers.

[Rob Evans @internetplumber]

@mneylon @ripencc You’d hope so, but some of the pricing publicly available suggests larger blocks attract a higher per-IP price. However you’re right, there’s probably a sweet spot of around a /16.

Hmm, should I pay for @TravelodgeUK hotel wifi (5Mbps down, 1Mbps up), or use tethered 5G (77Mbps down, 49Mbps up)?

[Rob Evans @internetplumber]

Fingers crossed. https://t.co/M6czwN7V5D

@portfast Oh I remember that well. This one, right? https://t.co/4XTyS5DrND

OP: "Anyone having issues with NTP across AS6453?"
NANOG: "Why don't you use GPS or have your own atomic clock for your stratum 0?"

@peterrhague @molmutius * _your_ IT service

[Rob Evans @internetplumber]

@peterrhague @molmutius OK, the usual approach would be for you to talk to our IT service and they could raise a ticket with the Janet Service Desk, but if you drop me an email ([email protected]), I'll see if we can get the right people involved.

[Rob Evans @internetplumber]

@peterrhague @molmutius First thing we'll need to understand is the end-to-end path, but one of the reasons we set up the network performance group was to try and find out who was still shipping boxes of disks around and to see if we could solve that.
