Yup .. 1.8 ms is extremely close, which is usually good news.
Youtube runs some pretty complex calculations to determine where to send you traffic from – only some of which I’m sure folks have figured out and/or it’s been made public. When folks say “Youtube isn’t working”, there is no simple answer unless of course you have access to their systems to better understand. It could be connectivity issues between you and the origin server, mapping issues at Youtube (sending you to the wrong place), a specific server in a cluster acting up, among other things. I will say that in my experience with their caching servers, they work very well overall. Nothing is perfect but I’ll take 99% of the time any day :) On Wed, Apr 8, 2015 at 4:09 PM, Bill Prince <[email protected] <mailto:[email protected]> > wrote: When I use that URL, I don't get any of the next_hop or loopback information. It just lists my IP plus the "=> sjc07s17", then my IP in parenthesis. Nothing else. So, using your formula, I plugged in that cluster name into a traceroute, and got 1.8 ms round trip time. I think that's good, or at least above average. bp <part15sbs{at}gmail{dot}com> On 4/8/2015 9:08 AM, Paul Stewart wrote: Sorry – no idea on that one….
