Hi all,

This morning we stopped a DDoS attack on our mirror coming from China. 
The traffic was somewhat similar to what we've discussed in the past[1], 
except this time they weren't range requests, they were downloading the 
full iso files. The worst offenders were 223.67.0.0/16 and 
182.255.33.0/24, in case you want to check your mirrors for signs of abuse.

Cheers,
Alex
