I am managing a website where a dynamic landing page, due to a badly written/optimized code, often times out after a few seconds and shows a blank. After refreshing, the page loads but it usually takes long time.
To assess the issue, I am looking at the avg. page load time in GA at Behaviour/Site Speed/Page Timings and I can see a value of 11.62 sec.
Does this value contain any data about page loads that timed out before they could finish loading?
In case not, is there a way I can see any data about the page's time outs (for example how many user sessions were affected by it)?
Many thanks.
