Web traffic dig up abnormally

We always find web traffic dig up abnormally within 1 or 2 hours

Majority came from the ASN of HWCLOUDS, ALIBABA, TENCENT, the source IP addresses are likely their proxy, which have no bad reputation, and those requests distribute across several IPs evenly

usually their path is “/”, methods is “GET”, User agent is iPhone

Any experience about that situation, they are bad or not bad?
