Hi,
we have some agents with Internet Explorer 10 (most actual verison) and urlblast 365 like yours on Dulles-location. Tests on these agents with HTTPS deliver waterfalls without any ssl-negotiation-times, at all. Same test on other agents with IE8 and/or FF 23 delivers ssl-negotiation-times like expected.
Same test on webpagetest delivers ssl-tmes, too:

Any idea, what could cause this?
