I was really pleased to see a Singapore host had been added - luckily performance for our site from Singapore looks pretty good.
However, I noticed a strange issue in the waterfall output from the Singapore IE8 host: the CSS and JS files often (but not always) display “0ms (Request canceled)”, and then appear to be immediately re-requested. This doesn’t seem to impact performance at all - which is odd in itself, since it seems to indicate that the browser canceled and then immediately re-issued the request, since “0ms” is certainly less than a RTT latency.
It turns out that the Dulles IE8 host also exhibits this behavior - hadn’t noticed it before since it doesn’t actually seem to impact performance:
Server logs only seem to show these files being requested once for these page views.
Anyone have any ideas what’s going on?
