No. Just tried it in chrome and it is still loading while I am typing this. It was ok at work via Orcon. Strange. The real problem is the maps on Geocaching.com and a wife who needs to know where the new caches are NOW....
Chrome now says "This webpage is not available"
There is no https option for maps.google.com to bypass the Slingshot proxy
Ok some more testing. I have connected to a PC at work via VPN and remote desktop and used that PC to connect to google maps. Work PC is via ORCON and speedtest.net returned 21Mbits/sec Using IE it came up quickly and was usable. Facebook at home via slingshot is also unusable. Slingshot returned 7MBits/sec
I still don't believe it's the raw line speed it the issue.
