The area he was in was served by satellite internet access, and experienced significant latency (a floor of 506 milliseconds) and packet loss (between 50-80% was typical). To counter this, the school he was visiting sets up their own local caching server. I use T-Mobile, which is normally excellent. But it’s all roaming.

To reach an individual you will look up him or her in your address book, and select a phone (home, work, mobile) and then a number to dial.

For a busy page with lots of external resources (like perhaps a news website with loads of ads and trackers), there might be dozens of DNS lookups required per page. The browser caches the results of these lookups, but they can be slow. You might think of a prefetch as being a bit like adding a file to the browser’s cache.

A few months back, I was pulled into a scenario where a business has been working with a leading CMS vendor to roll-out a network of multi-regional websites. If you put your whole website on CDN, technically you don’t need a large number of server infrastructure and CMS licenses.

Typical use cases for a relational database include web and mobile applications, enterprise applications, and online gaming. Use cases such as gaming, ad tech, and IoT lend themselves particularly well to the key-value data model where the access patterns require low-latency Gets/Puts for known key values. Take Expedia, for example.

The risks embedded in these deep-wetware effects, and their cross-origin implications, mean that your website's success is partially a function of the health of the commons.

Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. Latency can be roughly defined as the time it takes to send a packet from point A (say, the client) to point B (the server). Two-way latency is often called round-trip time (RTT).

You’ve probably heard things like: “HTTP/3 is much faster than HTTP/2 when there is packet loss”, or “HTTP/3 connections have less latency and take less time to set up”, and probably “HTTP/3 can send data more quickly and can send more resources in parallel”. Websites would magically become 50% faster with the flip of a switch!
