chinese routers are back

if you've been experiencing big spikes in transit traffic, anal leakage, or low tunnel creation success rate, the chinese routers are buzzing around again

At about 9 AM UTC yesterday, Mon. Oct. 21, we saw a dramatic increase in network activity that knocked about 10-15 percentage points off the Java exploratory build success network average.
Both Java I2P and i2pd routers saw an increase in participating tunnels, participating bandwidth, and known routers, and users have made inquiries on Reddit and IRC about it. Most users saw a decrease in tunnel build success on both implementations.
We believe the source is a known fleet of Chinese routers that we have been monitoring most of the year. These routers reappeared in two groups, on Oct. 12 and Oct. 16, and then started the aggressive tunnel building yesterday. This is the first sign of a large-scale attack since the last round ended about June 4.
As Java I2P and i2pd have different congestion control implementations, the effects on your router may vary. For either product, if the bandwidth or CPU currently used is more than you wish to contribute, reduce your total bandwidth limit or share bandwidth limit configuration.
At this time, we do not believe that the integrity or security of the network is at risk, but we continue to investigate. As usual, please ensure you are running the latest version (whether Java I2P or i2pd) so you have all the mitigations we've developed. -zzz
