can't ping google (at random)

For the past couple of weeks I've noticed an odd behavior.
I would google a string and it would spin for ages .. I'd cancel and restart and it would come back straight away.
Later still it would take maybe a dozen such restarts before it would instantly reply.
I've seen this behavior before, where routing tables have become corrupt and requests simply route to the bit bucket.
I decided to investigate:

$ nslookup google.com
Server:         127.0.0.1
Address:        127.0.0.1#53
Non-authoritative answer:
Name:   google.com
Address: 209.85.227.105
Name:   google.com
Address: 209.85.227.106
Name:   google.com
Address: 209.85.227.147
Name:   google.com
Address: 209.85.227.99
Name:   google.com
Address: 209.85.227.103
Name:   google.com
Address: 209.85.227.104

$ ping 209.85.227.105

As can be seen one of the address coming back fro Google seems to not be reachable.
So either 209.85.227.106 should not be in the list (DNS problem) or should
be there but is just not pingable from plusnet network  (and not  httpable etc)
so can other folks ping 209.85.227.106 ... can you http://209.85.227.106 ?
