SqueakMap proxy error

Hi,

Having not seen this on the list today, I realize this may be something to do
with my network .. but after digging some, it seems not, so I will ask

Attaching to SqueakMap:

http://map.squeak.org/

I get

Proxy Error
The proxy server received an invalid response from an upstream server.
 The proxy server could not handle the request GET /.
 Reason: Error reading from remote server

Anyone else seeing this?

Thanks Milan
