Yesterday Yahoo shut down the legendary internet service GeoCities, which they bought back in 1999 for $3.57 billion in stock. While this does not appear to have anything in common with Yahoo Mail, it seems like the shutdown of GoeCities might have caused an outage for Yahoo Mail.
Andrew Molyneux, Program Manager at Yahoo Mail wrote on YMail Blog that “[a] small fraction of Yahoo! Mail users may have experienced intermittent email issues earlier today, October 26, but the problem has now been resolved.”
