These are the relevant statements from the ISK-FAQ: (1) As dynamic (AYIYA and heartbeat) tunnels won't be up all the time it will only receive a 5 ISK bonus after it has been created for one week. (2) After that uptime credits will be given every two weeks when the tunnel is alive. (3) The host pinged yet another week credits 5 (last entry of cost table) (4) The above list shows the default credit costs, each PoP can have their own set of costs. But unfortunately they are not that clear, that they should be. For example, according to (2) and (3) one should get 10 ISK every 2 weeks. But the truth with my tunnels is, that I only get 5 ISK per 2 weeks, but may be that is because of (4). Not mentioned in the ISK-FAQ, butseen in some forum contributions and as far as I understand: (a) If the tunnel is dead (does not reply to pings from the PoP) for more than one day, the counter for aliveness is reset to zero. So you must run your tunnel for 2 weeks at least one time every day, to get the next ISK charge. (b) The measured latency of your tunnel during aliveness must be below 100 ms for most of the time, but I don't know the exact criterion that leads to a failure to meet this condition.

Sorry, I didn't read your contribution exactly enough. You talk about a static tunnel, where other/additional conditions are in force. But nevertheless, there is still some uncertainty about the exact rules that govern the wins (and in your case also the losses) of ISK.

Thanks so far. Even though it is not exactly clear how to interpret the uptime of the tunnel, in my case I know the tunnel is up for more than 17 days without interruption. So in my opinion I should have earned some ISK's Lets wait a few more days..

For me it looks like if there was a problem in the ISK system begin of may. I have 2 tunnels up since 14 weeks now but according to log I did not earn ISK after 12 weeks uptime. But it does not bother me much because I have enough ISK at the moment. Greeting from Bisamberg Hannes
