Want your geoblocking to actually be semi-useful? Make sure your application prefers . I’ve got four services that I regularly use but are geoblocked from my current location. One (IPv4-only) VPN connection later and I’m in.

Hm... gotta love being overseas when the office router fails. Thankfully, the management network is shared with the lab and I was able to get the lab router reconfigured remotely with a new VRF to take over for it.

@aconaway I can do that, but probably not on any of the cloud providers you want me to use.

"Just create everything in $cloud_provider the way we have it in the data center. What's the big deal?"

I'm still up because our DC vendor decided to migrate our Internet link without telling anyone. This included an redundant interface that was down that became the VRRP master. After telling them to flip over to the VRRP backup router, everything came back up.

"Head of CERT asks if we use BGP. "

"Well, ... yes !?"

"A probably service impacting vulnerability has been discovered quite recently."

"I know, but we're not affected by this."

"Huh, how do you know?"

"I follow the guy who investigated these flaws in BGP error handling on and read his blog twi days ago"

"Masto ...what?"

The @mikrotik RouterOS VRRP virtual interface (as opposed to virtual address) is refreshing and has been very useful thus far.

Following up on this, when the KISS principle is applied to a system, simplicity is measurable. If we try to factor in individual understanding, it isn’t. Another practitioner might see an approach that that breaks my brain as elementary and vice versa. We shouldn’t be using KISS as an excuse to scale static routing (for example) because a practitioner might not understand routing protocols.

KISS is an operational principle. It’s about not introducing unnecessary fragility into the system. It’s not about catering to a lack of understanding on the part of practitioners. That’s what comments and documentation are for.

DBAs: There's a network problem!
NetEng: No, there isn't. You're the only one having issues.
SysEng: The system logs say your SQL process keeps dying. What changed?
D: We only changed X. It shouldn't affect anything.
Everyone else: ...

This needs saying every so often. Neutrality and agnosticism are •not• the same thing. If I’m vendor neutral or platform neutral, I don’t have a preference. If I’m vendor agnostic or platform agnostic, I •literally• have no knowledge of either.

Me: You’re •absolutely• sure that these ExpressRoute gateways aren’t in production, right?
Them: Yup. They’re just for testing at this point.
Me: Good. I’m going to switch to vwan gateways.
Them: Go for it.
Me: (Deletes vnet gateway.)
Customer: Our Internet is down!

I'm doing some today. I've got to add some functionality to an inventory script so we can get routing protocol information stored somewhere in . Also need to figure out how to store that.

Demo: *pings hostname that doesn't resolve*
Them: Did I type it right?
Them: *copies name from CLI and pastes it into a browser*
Them: Must not have typed it right.
Me: *wonders if you understand how name resolution works*
