i wonder on who's fault this is...

i have 2 mirc 6.17 connected from my pc constantly online
one is me, second is bot.

and today i look at channels on 1st mirc that i use and i notice
that during night i was disconnected 7 times from network
with ofc this glorious message...

while looking on bot (mirc 2) nothing happened...

wouldn't be logical that they both died 7 times at same time
if it was due DSL modem or ISP ?
