Besides apology, Google also mentioned a number of reasons which were responsible for bringing the services to a halt for a while. JPN
On 24th January, a number of popular Google services like Gmail, Google+, Calendar and Documents were hit by a technical snag and it has been learnt that around 10 percent users had to face the problem for around 25-30 minutes.
Let’s have a look at what went wrong. An internal system, which generates configuration - information on how other systems should behave went on to generate an incorrect configuration due to a problem in software. The incorrect configuration made its way to live services for the next 15 minutes. This ignored the users’ requests for their data and the services generated errors.
As the users discovered errors on affected services, the internal monitoring team of Google alerted the Site Reliability Team and after working on the problem, a new and correct configuration was sent, which rectified the errors.
Once the services got back on track, Google has ensured that it will take steps to avoid such issues henceforth and in its Google+ post, it wrote – “we are putting more checks and monitors in place to ensure that this kind of problem doesn’t happen again.”
Besides apology, Google also mentioned a number of reasons which were responsible for bringing the services to a halt for a while.
