Re: google compute engine health check or DoS?
Good morning, Jimmy-
Thanks for https://cloud.google.com/support/ reference. I see many
unanswered questions, though ;-)

After changing DNS to CloudFlare's, I did not notice any
improvement(s). Thus at around 23:11pm I rebooted (with gcutil
resetinstance) and subsequently I was able to log in via gcutil
(indeed ssh functions, too).
Analyzing syslog it seems that the GCE instance began having issues at
around 18:54 pm beginning with the line:
Mar 21 18:54:34 my-gce-instance kernel: [3502320.420053] INFO: task
kswapd0:18 blocked for more than 120 seconds.
[...]
Accordingly, issue that began this thread appears to be kernel
related; I have sent you an edited version of syslog (leaving the
kernel related stuff intact) in case you want to analyze it.
uname -a
Linux my-gce-instance 3.2.0-4-amd64 #1 SMP Debian 3.2.54-2 x86_64 GNU/Linux
Although my GCE Console graph shows sustained spikes, the range of
values seems normal; thus, it was not a DoS/DDoS after all.
Best Professional Regards.
