comment Varnish as a cache proxy on openshift-online : openshift limits number of requests from same IP?
Sure, okay, that could happen if you have a cached copy eligible to be served to your loopback connection, whereas your browser was unable to hit the backend. That would require you to have configured backend health checking in your Varnish VCL, though; by default, Varnish doesn't monitor backend health. If you can get it to happen again, varnishlog output would tell you exact how and why Varnish is routing (or not) the request. You can also check the "Age" header you are receiving, or add a cachebreaker (e.g. ?abc123) to the URL, to make sure you aren't getting a cached response.

comment System not being able to handle soft interrupts but having idle time?
At the risk of being dismissive of your question, I want to clarify: ksoftirqd doesn't indicate that soft IRQs are being missed, it indicates that soft IRQs are happening often. In fact, ksoftirqd running is an indication that soft IRQs are not being missed!

comment Apex ANAME / ALIAS record in Windows Server 2012 R2 DNS Manager
Yes, SRV is lower in the list, but the selection logic is rather complicated; if Outlook doesn't like the answer it gets from an earlier stage, it'll try later ones, and then circle back to the original if it can't find a complete answer from those later stages. Certificate mismatches are an example of this, if I recall correctly; if it finds Autodiscover.xml but it has a cert mismatch, it'll keep going to see if it can find it without a cert mismatch, and if so, it'll present the latter.

comment How might I cancel scheduled downtime on Nagios
Fair point. Deleting a downtime, however, has a far larger effect on reports, no?
