zzz has posted the following update:
“I2P network reliability is currently degraded due to a novel and persistent attack. Please be patient as we work on mitigations. If you have not yet updated to the latest release 2.5.0, please do so as it provides some defences.”
For i2pd users, you can try building their latest from GitHub which may help.
Also team Java, similar data, just saw I had an update waiting. I’m too paranoid about memory corruption to run i2pd.
