We use the Google Map API, and it appeared that Google was unreachable here for several minutes. In that time, our Observium box ground to a halt due to all the PHP processes hanging on what I can only guess were map API calls. Once Google came back the machine became responsive again after all the processes finally cleared out.
What is your dns server?
Sure its good?
We use google's own 8.8.8.8

Not a DNS issue. We could ping google, but HTTP/HTTPS connections were not going through. Checked with third party monitoring systems and they also reported the same state

Ok the speed of the google maps is based on the CLIENT.
I just did a wireshark on my client browsing Observium and on the Observium server.
The server didn't go to any dns while my client did.
See attached;
So my question - how fast/well can the client access these api's. google probably has a team of 500 people keeping them up and fast 24 x 7 :)

Hahaha.

The webserver doesn't communicate with Google when generating the map, that's done in the browser.
I've noticed that Chrome does some strange things in unforeseen circumstances causing problems for web servers, though.

The polling system uses geolocation to calculate the LAT/LONG as well as fill out the location information for the device. This is what was most likely hanging and driving the load through the roof.
