Yesterday I've received some mails via this Blog that asks me if I know that some "priviledge" Gmail users have the capacity of their mailbox increased to 1Terabyte. My response was that I don't know this and maybe it could be a bug.
Today the official answer by Google: A "bug" in Gmail temporarily gave some users one Terabyte of free storage and now the company is working to fix it. I was right!
