Exchange rate sometimes inexplicably 1.0 about currencies HOT 5 CLOSED

I've got $100 for anyone who can replicate it and show a solution (not just a workaround).

from currencies.

Here's the smallest bit of code that will produce the inconsistent results. It only does it on my production server, not on my development machine (not even in production mode).

rails@li354-33:/srv/tinefcon-orders/current$ ./script/console production
Loading production environment (Rails 2.3.8)
>> ["AUD", "CAD", "EUR", "HKD", "PLN", "RUB", "ZAR", "GBP", "USD"].map {|c| ISO4217::Currency.from_code(c).exchange_rate }
=> [1.0, 0.6493, 0.8819, 0.0787, 0.2209, 0.0221, 1.0, 1.0, 505571776.0]
>> ["AUD", "CAD", "EUR", "HKD", "PLN", "RUB", "ZAR", "GBP", "USD"].map {|c| ISO4217::Currency.from_code(c).exchange_rate }
=> [1.0, 0.6493, 0.8819, 0.0787, 0.2209, 0.0221, 1.0, 1.0, 505571776.0]
>> exit

Mystery solved. It's actually coming from Yahoo that way.

?> ["AUD", "CAD", "EUR", "HKD", "PLN", "RUB", "ZAR", "GBP", "USD"].each {|c| puts get_yahoo_response(c) }
"AUDGBP=X",1.00,"N/A","N/A"
"CADGBP=X",0.6494,"7/21/2011","12:59pm"
"EURGBP=X",0.8821,"7/21/2011","12:59pm"
"HKDGBP=X",0.0787,"7/21/2011","12:59pm"
"PLNGBP=X",1.00,"N/A","N/A"
"RUBGBP=X",1.00,"N/A","N/A"
"ZARGBP=X",1.00,"N/A","N/A"
"GBPGBP=X",1.00,"N/A","N/A"
"USDGBP=X",0.6134,"7/21/2011","12:59pm"

Now to figure out why.

I'm going to use https://github.com/RubyMoney/eu_central_bank instead. So long and thanks for all the fish.

Sorry for the slow response, I have been planning my wedding and very swamped. I will take a look at Yahoo and see if they changed something or are just mucking it up.
