<br />
This issue has been running for several days and finally I decided to check the stats: we have noticed a sudden increase in bandwidth used by one of our mirrors.<br />
<br />
Our other mirror's traffic pales compared to this one. A sustained traffic of 600-800mbps when others hardly reaches 50-70mbps.<br />
<br />
We checked the stats and noticed that the most downloaded file, summing up several TB is CentOS-7.8.2003/isos/x86_64/CentOS-7-x86_64-Everything-2003.iso, it has been downloaded several times summing up 5.21TB in the last 7 days.<br />
<br />
BTW 5.21TB of the traffic from this mirror goes to China.<br />
<br />
One single IP: 112.95.214.226 has tried to connect to our mirror 17516 times. And in sum 8 IPs from China has actually downloaded several CentOS isos in the last 7 days: in total we have served 26113 connections only to access .iso files (CentOS-7 and CentOS-8) from those 8 ips:<br />
<br />
112.95.214.226 - China Unicom Guangdong province network<br />
223.88.61.170 - China Mobile Communications Corporation<br />
171.41.7.29 - CHINANET Hubei province network<br />
120.84.10.190 - China Unicom Guangdong province network<br />
27.221.66.104 - China Unicom Shandong province network<br />
27.221.66.105 - China Unicom Shandong province network<br />
112.32.21.93 - China Mobile Communications Corporation<br />
27.221.49.135 - China Unicom Shandong province network<br />
<br />
Have you noticed that in your mirrors? look for these IP and notice if they have been trying to continously download iso<br />
<br />
BTW: Why is centos-8.1.1911 isos being served even when centos-8.2.2003 has been available for a long time? Why isn't centos-8.1.19.11 being moved to vault?<br />
