The I2P network is currently under a Denial-of-Service attack. This attack affects I2P and i2pd but in different ways and is having a serious effect on network health. Reachability of I2P sites is badly degraded.

Java I2P users are suggested to disable the sybil attack tool, delete the sybil-blocklist, and re-start their routers.

To disable the sybil attack detector tool

Open the sybil attack detector in your router console at http://127.0.0.1:7657/netdb?f=3&m=15

Change "Background Analysis Run Frequency" to "Never"

Click "Save" to save the settings.

To delete the sybil blocklist, run:

On Debian and Ubuntu:

rm "/var/lib/i2p/i2p-config/sybil-analysis/blocklist-sybil.txt"

On other Linuxes and on Mac OSX:

rm "$HOME/.i2p/sybil-analysis/blocklist-sybil.txt"

And on Windows:

del %LocalAppData%\i2p\sybil-analysis\blocklist-sybil.txt"

When you are finished, re-start your I2P router.

If you are hosting a service inside I2P and it is hosted on a Floodfill router, you should consider multihoming the service on a Floodfill-disabled router to improve reachability. Other mitigations are being discussed but a long-term, backward-compatible solution is still being worked on.
