Fark me 🤦♂️ I woke up quite late today (after a long night helping/assisting with a Mainframe migration last night fork work) to abusive traffic and my alerts going off. The impact? My pod (twtxt.net) was being hammered by something at a request rate of 30 req/s (there are global rate limits in place, but still…). The culprit? Turned out to be a particular IP 43.134.51.191 and after looking into who own s that IP I discovered it was yet-another-bad-customer-or-whatever from Tencent, so that entire network (ASN) is now blocked from my Edge:
+# Who: Tentcent
+# Why: Bad Bots
+132203
Total damage?

61k reqs over an hour or so (before I noticed), bunch of CPU time burned, and useless waste of my fucking time.
