Apologies for the ongoing infosec.town troubles. I am not certain of the cause, but the issue is with the redis cache. After some period of time, the site slows to a crawl, but after flushing the redis database, it's very fast again... until next time. I created an automated job to flush the cache, but I have to keep reducing the amount of time between flushes. Currently it's at 4 hours and I'm going to reduce it to 1 hour (note, it started at weekly a few months ago) so it definitely it getting worse.
