Building the internet - layers 1 through 9

@bettersafetynet @slippyfox Live migration is definitely possible on Proxmox. It does have dependencies on the storage being used.
Ceph is the advanced option if you're doing complex clusters with a large fleet.
A simpler option is to just use ZFS for your local vmdisk storage.

@TracketPacer In a joking manner, fiber is life!

The literal answer https://t.co/r9LFBdfwuv. It's surprising how much one can learn from this talk.

@mrhameljr @TracketPacer Richard updates this presentation every few years and it's an excellent resource.
I've made every new team member watch it... Multiple times over if necessary

@nickhedley @JK_ZA The lower stages of load shedding due to the Steenbras Hydro Power Station probably reduce the demand for solar installs in CoCT. Cape Town users experience minimal inconvenience from load shedding up to (Eskom) stage 3

@nickhedley @Arfness Thyspunt in the Eastern Cape was announced a few years back. There still seems to be ongoing activity by Eskom to obtain a nuclear operating licence from the regulator for the site. Multiple fumbles though.

We do 32GB standard. 🤷‍♀️

@troyhunt @awlnx @haveibeenpwned Companies I've worked for have a process for that, but also load it up with so much bureaucracy that staff choose to just absorb the cost. For a few meals it's no problem, for a regular payment its a perverse incentive to push bureaucracy on others to avoid more of your own admin

@adrianfrith Looking at the population age graphs from the previous census there seems to be a weird spike at 25-29. Is this something that is easily explained or something we need to watch?

[Graham Beneke @GrahamBeneke]

@dtemkin Did some napkin maths around this for an FTTH network to look at the risk Starlink posed to business:
Each Starlink satellite can support 2000-5000 households with a fibre-like service. Even at suburban density they could not launch enough satellites to displace fixed line

@erikbryn @GalileoSats Why does this profile correlate with the Northern hemisphere summer? Is the average being calculated using more Northern data points? Is the planet warming more overall during Northern summer? Something else?

@meileaben @atoonk @heymingwei Many of the IXs are running their own peering LAN systems on virtualised infrastructure. If the collector can be packaged up as a VM image then it could certainly be abstracted away from the physical hardware and logistics challenges.

[Graham Beneke @GrahamBeneke]

@atoonk @heymingwei Using multi-hop has other challenges: you're dependant on a lot of intermediate networks and you'll lose connection and data streams during disruptions - which has historically been some of the most valuable RIS data.

[Graham Beneke @GrahamBeneke]

@TracketPacer In the past many switches would drop them - but then came Q-in-Q and dotQ tunnels. For a while this had to be explicitly enabled on the ports. These days the default config on many devices will just add the tag specified on the port and carry the resulting double tagged traffic.

@woodyatpch @GuyHalse can you help with GINX? The online record is almost completely gone

[INX ZA @inx_za]

We are pleased to announce that our next #community run #IXP will be the Nelson Mandela Bay IXP (NMBINX) in Gqeberha, Eastern Cape. Go live will be first week of June.
If you're new to #peering be sure to attend one of our training sessions, to make sure you're ready to peer!

@MalwareJake Ignoring the license USB... What is the equivalent for read-only media like DVD in 2023? Something which is not going to raise red flags in air gapped environments.

For those who missed Mr Graham Beneke's presentation on "Scrapping 3064s... and other Layer-2 best practices" at #ZANOG23, we've got you covered!

[Graham Beneke @GrahamBeneke]

@danieldibswe If your network availability target is in the three 9's (99.9%) ballpark then stacking is probably fine. It severely limits your options for concurrent operation during many types of maintenance. You should not be leaving a device for years with no software updates anymore.

[Mike Stopforth @mikestopforth]

The burden and privilege of leadership is accountability.

Sadly most people think leadership is having the power to blame subordinates for your mistakes.

[Sean Wright @SeanWrightSec]

Mandatory password changes are stupid! I’m now locked out of my computer because of one. Please explain how this helps security?
