Having weird issues with the data reader fetching yahoo finance

[xrlu0929]

`import pandas_datareader as pdr
import pandas as pd

import matplotlib.pyplot as plt

import datetime as dt
start_date = dt.datetime(2016,1,1)
end_date = dt.datetime(2016,12,31)
df_bit = pdr.get_data_yahoo('GBTC', start_date, end_date)
df_gd = pdr.get_data_yahoo('IAU', start_date, end_date)
df_com = pdr.get_data_yahoo('IYZ', start_date, end_date)
df_bio = pdr.get_data_yahoo('RYOIX', start_date, end_date)
df_tao = pdr.get_data_yahoo('TAO', start_date, end_date)
df_sp = pdr.get_data_yahoo('^GSPC', start_date, end_date)`

Then it returns：

You're not alone... see #315, #330 and PR #331

@rgkimball Oh My.... I've tried searching for new tickers, and even restart...but no.. It worked yesterday, just today when I wanted to look into some issues to finalize it, then it shows like this!
Thanks, I'll go and see the issues you mentioned to try luck.
