We had 30 minutes of wiki downtime starting from SJ's report at 1755 EST<br>
today. Chris and I responded by:<br>
<br>
1. pinging wiki.l.o, which was responsive<br>
2. connecting to weka and examining top, which showed squid2 pegging<br>
the CPU.<br>
3. Following the instructions at [[Machine:squid2]], connecting to<br>
squid2.<br>
4. observing via top that squid was consuming 100% of the squid2 VM's<br>
cpu.<br>
5. stracing squid looking for clues<br>
6. installing and running tcptrack to check out network conditions<br>
7. reaching no conclusion about the cause of failure and<br>
8. running /etc/init.d/squid restart, which restored service.<br>
<br>
