"Search options, such as displaying of currency exchange rates, are based on data from external sources," Google Poland said in response to questions sent by tvn24.pl's business section. On Monday (Jan. 1) evening, indexes at a number of websites, including Google, indicated the euro exchange rate at 5.73 PLN. Shortly after, Poland's Finance Minister Andrzej Domański said this information was "fake" and caused by a date source error, reassuring that there was no reason to panic. Had the fake information been true, it would have meant there was a 32% increase compared to Friday's closing.
