Server is slow for me in the past few days. Anyone else feeling the same?

Did you upgrade Lemmy on the 13th or something? Could be a new bug.

Also, did site traffic increase at all? Maybe there's an AI scraper messing up.

    I did not update or change anything in the past few days.

    But, now that you mentioned an AI scrapper I looked into the logs and noticed some heavy requests to the API from a specific IP.

    Requests look consistent to scraping - just consistently and continuously issuing GET requests to different API endpoints.

    XX.XX.XX.XX - - [14/Oct/2025:21:28:54 +0000] "GET /api/v3/community/list?limit=20&sort=TopAll HTTP/2.0" 403 107 "-" "Mlmym"

    I have started denying their requests and it is the first thing that seems to have actually helped!

    I don't want to speak too early but I think you may have identified the cause. Thanks!

    I just realized that it is not a 'scraper', the requests came from the server that I am using to provide an interface to the site as an Onion site. The amount of requests was suspiciously high so maybe a bot is scraping through Tor. I will leave it off for a few days and see if I can turn it back on later.
