This is a good point to check. I did so and comments.php does show expected IP addresses (not just localhost). I don’t claim that this is not an artifact of my particular setup, but I have other plugins that do show the origin IP correctly.

To be clear, this is a fairly common issue, so I’m not picking on the ARYO plugin; there are many other plugins that have the same issue. In fact I raise it only because ARYO is the best logging tool I’ve seen for my purpose (I realize there are specific security-oriented loggers, but I like the particular features of this one). I’m no expert but I think that obtaining the true IP address is just a matter of looking at the right tag, e.g. X-Forwarded-For. I’ve seen it discussed in a number of places in WP forums and elsewhere, e.g.

I am guessing that this is to check for updates to plugin. The weird thing is that cloudapp.net is a domain used by W*ndows Azure cloud services. What is wordpress doing using a W*ndows service??? Surely there are better (and to the point, more appropriate) cloud services out there.

Had this problem as well. This was NOT caused by an upgrade or any other change; this is 100% caused by the maintenance mode plugin’s back end. I neither upgraded nor made any other change to the site configuration, but my users started reporting problems about 8 hours ago (the same time this thread started). Setting the ‘support’ option to false didn’t work for me, I had to disable the plugin entirely.

The culprit is the lrss_check_update() function in key-check.php (see MadMakz’s post above). New Relic monitor confirmed that in every case lrss_check_update hangs and times out after 120 seconds (that being the default for my particular configuration):

Component		Total(ms)  %	Max(ms)	Call count

lrss_check_update	120,000	99.8%	 120,000	1
Internal fun...	 	41.1	0.0341%	 41.1	 	1
apply_filters	 	15.1	0.0125%	 0.15	 	3,490
wpdb::query	 	12.5	0.0104%	 1.45	 	32
get_option	 	6.66	0.0055%	 0.04	 	339
translate	 	5.67	0.0047%	 0.02	 	1,010
etc.

WTF??? I won’t be using this plugin again. Ever.
