> a secret DoD plan to convert FedEx's fleets

There is the Civil Reserve Air Fleet, of which FedEx is a member.

Why are you so confident there’s a big problem to solve here?

There will never be guarantees.

The "up to 48 hours" is commonly used because that's the ttl of many things that matter. For instance, NS records for names in the .com zone have 48 hour ttls.

You can give better estimates to your users if you know the state you're transitioning from. For instance, a brand new .com domain would be 15 min negative ttl plus the .com zone file update frequency.

What problem are you encountering?

I worked on dns gslb for a long stretch at Facebook^WMeta, and didn’t see an excess of bad actors. The vast majority of users follow our dns changes in an orderly fashion. Most delay sources to clients themselves.

> They probably just readjust their currency hedges

How would you propose that work? Hedging currency risk against unsold product isn’t a hedge, it’s a directional bet.

> it seemed to be CPE like modems and sometimes wireless routers that were blocking packets

Agreed. I think D-Link devices were some of the most common we saw.

Just as a heads up, zero in the last octet results in general reachability problems. We used x.y.z.0 as a vip at Facebook^WMeta for a while, but learned the hard way that some people can't reach those ips.

Adjustable rate mortgages and people who need to move who are now underwater. I couldn’t easily find nationwide stats on ARM issuance, but a quarter of First Republic Bank’s loans are adjustable rate.

Seems not.

Despite the name, there is nothing io-specific about the io_uring interface. Non-io syscalls can be added. Io syscalls just tend to benefit the most (due to call frequency).

> having the kernel execute consecutive systemcalls without switching the context

io_uring enables exactly this

The ebpf site doesn’t mention that because expanding the abbreviation is not helpful for understanding ebpf. The name is representative the past of ebpf, not its present use or future.

First I’ve heard of Cognizant. What’s their rep?

I thought this was going to be a slumlord starter pack.

> A fully qualified domain name includes a trailing dot

The term is ambiguous, and many uses don't include the trailing dot. See IETF RFC 8499 section 2.

> DNS is strictly ASCII-only

DNS is not strictly ascii. At the protocol level labels are octet strings. You may be thinking of the LDH convention.

Another possibility: the Mobilewalla data is bad.

The big problem, to the extent there is one, is between the client and the recursive server. Not as much the recursive and the authoritative. Cost is highly amortized between recursive and authoritative for busy names.

SNI is sent in the clear once per tls connection, not once per http request.

Ya, this is roughly what the fb apps do. Dns rarely blocks, and changes are seen quickly.

Some folks are using anycast to accomplish this, but that involves a different set of problems.

Siri depends on internet connectivity.

Why do you say they can be cashed in? US treasuries are generally nonputtable.

That's not correct. Not every subnet is a /24. Further, you don't necessarily need a network and broadcast address for a subnet. That's a local issue. See IETF RFC 3021 for one example of not having a network and broadcast address.

Zero in the last octet is problematic if you want to be generally reachable on the internet. We used x.y.z.0 as a vip at fb for a while, but learned the hard way that some people can't reach those ips.

Leap smear is how true time is defined in the roughtime spec.

This is so. Both passive and active connections are at risk.
