All Yahoo data stopped updating with the last data on 5/12. I get a errors like the following:

[6] CNP Error: The remote server returned an error: (502) Bad Gateway.
[7] CVX Error: The remote server returned an error: (404) Not Found.
[0] ^DJI Error: The remote server returned an error: (502) Bad Gateway.
[1] ^GSPC Error: The remote server returned an error: (502) Bad Gateway.
[9] ED Error: The remote server returned an error: (502) Bad Gateway.
[2] GE Error: The remote server returned an error: (404) Not Found.

Is this something that others are seeing or is this something that has changed on either my computer or my network?

A simple search can do miracles.
