Google outages blamed on sign-in system

Gmail, Drive and several other Google applications were affected for several hours this week

A malfunctioning log-in system affected millions of people's ability to access a variety of Google applications on Wednesday, including Gmail and Drive.

The problem, which lasted for about three hours on Wednesday morning, occurred when the main user authentication system for Google applications was misconfigured.

The improper configuration, introduced on Tuesday, caused log-in requests to be funneled to a small number of servers, which in turn ran out of capacity, and the overload caused them to malfunction.

"At the peak of the outage, this issue affected 50 percent of the Admin panel and 60 percent of Google Sync login requests. The percentages of affected users for other services were

lower such as 0.18% users for Gmail," reads an incident report Google posted on Friday.

Google fixed the configuration problem and will take other steps to help prevent the issue from affecting its systems again, including improving monitoring and alerts for server overloads caused by authentication-system misconfiguration. Google also plans to alter the log-in retry behavior of large systems like Gmail, so that they don't aggravate outages caused by server overloads.

The HP OfficeJet 250 Mobile Printer is a great device that fits perfectly into my fast paced and mobile lifestyle. My first impression of the printer itself was how incredibly compact and sleek the device was.

Wireless printing from my iPhone was also a handy feature, the whole experience was quick and seamless with no setup requirements - accessed through the default iOS printing menu options.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.
