That seems to indicate a normal enough delay. The site may be relatively
overloaded. There is also a possibility that the actual machine at that
address might simply be a fowarding address to a Google site in the
US. That's about a 6700 mile (10800 km) sort of delay time difference.

So far that shows no packet loss. I'd run the pings for a longer time,
say 100 pings or so, and look at the summary. If there are zero dropped
packets then Google should seem normally responsive to you.
