简介

I looked at a few “lessons learned from black Friday 2015” articles, but they’re all low on good technical detail. My consolation prize is this article that seems eerily appropriate, given Target’s outage on Cyber Monday.

The strategy of turning away only some requesters to avoid a full site outage is interesting, but I could see it causing a thundering herd problem if not done carefully, where folks just repeatedly hit reload and cause more traffic.
