Plesk on Lightsail Kernelcare Issue – /usr/bin/kcarectl –auto-update spam

I was receiving emails titled “Cron <[email protected]> /usr/bin/kcarectl –auto-update” with a body “The IP 1.2.3.4 was already used for a trial license on 2018-12-23”

At one point, I was receiving one of these per VM every four hours

As I’ve not got a licence anyway, this is easily solved with:

sudo apt-get remove kernelcare

AWS S3 Redirects with Cloudflare Page Rules – Fast and Free

A few weeks ago I used AWS S3 for 301 redirects, with Cloudflare on top to cache these requests, few as they were. This effectively maintains a handful of links which redirect somewhere useful, while directing all other traffic to this domain.

Stats from February for the site show 65% of requests were cached in the last week

The results are great! The switch to S3 was made on the 9th, and a Cloudflare page rule added on the 10th – at which point over 60% of requests became cached.
