Detailed post by @internetplumber@twitter.com about QSFP28 modules and laser diode degradation causing connectivity issues on a 100G port. Feels a bit like when a LAG member goes bad, which we wrote about faelix.net/news/201705/aggrava and became our most popular news post.

If you trust your web browser's WebRTC implementation then @jitsinews@twitter.com has got your requirements covered and your thread model addressed. We deployed a Jitsi Meet node โ€” free, open-to-everyone video conferencing โ€” a few days ago at faelix.tv/

RT @CHTJonas@twitter.com

Itโ€™s a shame that possibly the best video conferencing software, Zoom, also has an atrocious record on computer security vulnerabilities. Why is software hard? ๐Ÿ™ƒ

Good to see another email service provider has decided the same as we did for our CRM back in 2018: no more spy pixels! faelix.link/emailtracking

RT @dhh@twitter.com

@mailbrew@twitter.com I'm even happier to report that I was able to convince the team to forgo the spy pixels that any email startup would naturally default to. So there are no spy pixels in the Mailbrew sendings any more ๐ŸŽ‰โค๏ธ

Stretching the analogy: there are hosting providers that actually are wind-powered, and there are clouds that are as bad for the environment as cheap flights.

Using Google Cloud, AWS, etc always feels like I've rented an airport (but none of the people needed to run it) to fly a kite.

Early release of our Halophile Router project, presented @net_mcr@twitter.com, is up at faelix.link/hphr โ€” a @SaltStack@twitter.com-automated, @vyos_dev@twitter.com-powered template to deploy IRR- and RPKI-filtering, BCP38-compliant BGP routers for small ISPs. More info about it @uknof@twitter.com soon!

In addition to spraying our name onto the airwaves via the open SSID we run in every POP, we're also sticking our retro-futuristic logotype onto our cabs.

RT @NetworkMoose@twitter.com

Scarf Monty decided that the little printed label stuck onto the cab by the datacentre wasn't sufficiently "on-brand".

Somewhat optimistic estimate from 2010 โ€” networkworld.com/article/22273 โ€” suggests thousands of customers per IP address. For our any-UK-mobile-network 4G SIM product, we've started much more conservatively: ~100 devices per IPv4 NAT address.

@LTE_Max@twitter.com How many broadband customers do you think are doable for an ISP with a single /24 of space? Is 100 customers per IP doable? 1000 ?

Faced with exactly this challenge, and some others, we looked at @vyos_dev@twitter.com and we came up with: faelix.link/netmcr40 (4x10GE, 2x1GE, around USD$2000)

If you have a USD$4K to sub-$10K budget for a "full table" / provider edge router (aka can't buy a Juniper MX204) there are two options for you.

Hold off buying that $2500 CCR for just a few more months...more options are coming!! twitter.com/DrPeering/status/1

Linux kernel IPv6 neighbour cache entries cause a problem for a big name vendor โ€” and it feels worse than CVE-2018-19299 that @mikrotik_com@twitter.com fixed earlier this year!

Show thread

RT @ogelpre@twitter.com

Cisco found the bug in NX-OS: ipv6 neighbor entries are written into the neighbor cache of the underlying linux. But they get never deleted. With more then 250k neighbor entries things begin to break.
Workaround is a daily reboot of the switches.
