Two Days Worth of Problems for "Gfail"

Google's Gmail Should Be Working Again

Google says that Google Mail should be working again. Yesterday, Gmail went down for the majority of its 150 million users at around 1553 EDT, and was restored about two hours later.

The difficulties started on Monday when a small number of Gmail users had problems. Yesterday morning around 1120 EST, Google said that this problem was fixed for everyone but an even smaller group. 

Then the lights went out for Gmail.

According to this story at The Register, yesterday's problem was due to an "upgrade" to enhance Gmail performance and implied Monday's was as well.

Google has been suffering from a spate of operational performance issues this past year, leading some to start calling Gmail "Gfail."

Like it has in the past, Google said that it was "going to ensure this kind of event does not happen again."

Think of the many tasks to which computers are being applied that in the not-so-distant past required human intuition. Computers routinely identify objects in images, transcribe speech, translate between languages, diagnose medical conditions, play complex games, and drive cars.

The technique that has empowered these stunning developments is called deep learning, a term that refers to mathematical models known as artificial neural networks. Deep learning is a subfield of machine learning, a branch of computer science based on fitting complex models to data.
