We're deploying new bot, please wait... for a new result.

Fixed problems

We have fixed some remained problems.
The service now checks faster.

Bad day, new problem, not fixed

To day is so bad.
After upgrade our bot to new version, we did some tests to a large amount of YM buddies from out friend list.
Some are okay, but a little shows wrong results: The service say the buddy is offline when in fact, it is invisible.
We do not know why yahoo server response a wrong result >"< to only some ID

Maybe the service that does not fully supported by yahoo server.
We are trying to debug and try some other way to communicate with yahoo server.
So, please forgive if you test your nick but the result is not true.
Additional, please report your nick returned the false, it helps us to correct the bug faster.
Thanks

Cause there're many requests per second, sometime the result is not accurate (when it show offline).
So we added more bot today. You can find it checks very accurately.
