## AI overview

The author recommends an infographic about latency numbers, highlighting the contrast between SSD read latency and cross-site round-trip time. The article also mentions a website for checking latency from different vantage points and notes that the infographic can be fetched in a terminal with curl.

## Source excerpt

One of the key arguments against stretched clusters (and similar stupidities) I used in my Disaster Recovery Myths presentation was the SSD read latency versus cross-site round-trip time. Thanks to Networking Notes, I found a great infographic I can use in my next presentation (bonus points: it also works great in a terminal when fetched with curl) and a site that checks the latency of your web site from various vantage points.
