Happy New Year, .zoners!

We are now upgraded to the latest stable release of Mbin, v1.2.1. Check that link for a very nice changelog!

Separately, we’ve been running into server slowness and delayed receipt of messages. Because I lack any formal monitoring tools right now (should get on that), the task was to download the logs into Excel PowerQuery and look for any anomalies. Take a look at a summary below.

Issue: Slowness of received messages to the.coolest.zone, eventually leading to a delay of 2 days in recently-received messages.

Root cause: We found that a single IP address was scraping the website an average of 11.8 times per second with a maximum of 24 times per second. This was causing delays everywhere.

Corrective actions: We have learned how ufw-docker works (great instructions here!) and set a route deny rule for that particular IP address.

Future preventative actions: Now that I understand the www logs, it’s time to put in some monitoring so this isn’t fully a reactive process.
