More On Gmail’s Delivery Delays

Category: Gmail | Sep 24, 2013

Posted by Sabrina Farmer, Senior Site Reliability Engineering Manager for Gmail

On September 23rd, many Gmail users received an unwelcome surprise: some of their messages were arriving slowly, and some of their attachments were unavailable. We’d like to start by apologizing—we realize that our users rely on Gmail to be always available and always fast, and for several hours we didn’t deliver. We have analyzed what happened, and we’ll tell you about it below. In addition, we’re taking several steps to prevent a recurrence.

The message delivery delays were triggered by a dual network failure. This is a very rare event in which two separate, redundant network paths both stop working at the same time. The two network failures were unrelated, but in combination they reduced Gmail’s capacity to deliver messages to users, and beginning at 5:54 a.m. PST messages started piling up. Google’s automated monitoring alerted the Gmail engineering team within minutes, and they began investigating immediately. Together with the networking team, the Gmail team restored some of the network capacity that was lost and worked to repurpose additional capacity, clearing much of accumulated message backlog by 1:00 p.m. PST and the remainder by shortly before 4:00 p.m. PST.

The impact on users’ Gmail experience varied widely. Most messages were unaffected—71% of messages had no delay, and of the remaining 29%, the average delivery delay was just 2.6 seconds. However, about 1.5% of messages were delayed more than two hours. Users who attempted to download large attachments on affected messages encountered errors. Throughout the event, Gmail remained otherwise available — users could log in, read messages which had been delivered, send mail, and access other features.

What’s next? Our top priority is ensuring that Gmail users get the experience they expect: fast, highly-available email, anytime they want it. We’re taking steps to ensure that there is sufficient network capacity, including backup capacity for Gmail, even in the event of a rare dual network failure. We also plan to make changes to make Gmail message delivery more resilient to a network capacity shortfall in the unlikely event that one occurs in the future. Finally, we’re updating our internal practices so that we can more quickly and effectively respond to network issues. We’ll be working on all of these improvements and more over the next few weeks—even including this event, Gmail remains well above 99.9% available, and we intend to keep it that way!

Gmail for feature phone browsers gets a new look

Category: Gmail | Sep 9, 2013

Posted by Ari Bezman, Product Manager

People use all sorts of devices to access Gmail: their web browser, smartphone, tablet and, in many parts of the world, their feature phone. For those of you who use a feature phone to access Gmail on the go, starting today you’re getting a brand new look that’s faster and easier to use.

You’ll get a number of improvements that reduce the number of button presses required to read, reply and compose emails. For example, you can reply directly to a message from the thread view, you can choose to move to the previous or next conversation, and much more.

Making calls from Hangouts — in Gmail and across the web

Category: Gmail | Jul 9, 2013

Posted by Alex Wiesen, Senior Software Engineer

For those of you who have taken the plunge and are using desktop Hangouts in Gmail, Google+, and the Chrome extension, we’ve heard loud and clear that you miss the ability to make calls from Gmail, so today, we’re happy to announce it’s back – and better than before! Even better: calls to the US and Canada are now free from all countries where Hangouts calling is available. And international rates remain super, super low.
Today’s launch also improves the desktop calling experience in a number of ways. For example: you can add multiple phone numbers and video participants to the same call; and you can play sound effects (like applause or laughter) with the Google Effects app.

To make a call from Hangouts, just look for the new phone icon in Gmail, or for the new “Call a phone” menu item in Google+ and the Chrome extension. And of course: if you haven’t yet tried Hangouts in Gmail, you can always click your profile photo in the chat list and select “Try the new Hangouts.”
Making calls from Hangouts is rolling out over the next couple of days. As we’ve said before: Hangouts is designed to be the future of Google Voice, and making and receiving calls is just the beginning. So stay tuned for future updates.

New Google Groups now available to everyone

Category: Gmail | Jun 24, 2013

Posted by Ryan Falor, Product Manager, Google Groups

With Google Groups, you can manage a mailing list, coordinate with your social club, and find experts who share your interests. Over the last year we have been working on improving the experience and adding new features while keeping our old version running.

Today we’re retiring the old version and excited to be bringing the new Google Groups to everyone. If you haven’t tried Groups in a while you’ll notice improved options for managing your groups and long time users may be surprised by all the features we have added along the way.

One of the recently improved features is the ability to create an inbox that allows you to collaboratively share, distribute and track responsibilities with others. Imagine you and a few friends are organizing an event for your school and want a single email address to coordinate with vendors, parents, and volunteers. Members of the group can work together to manage email, assign items to each other, and mark items resolved. This can be a great feature for teams seeking a really simple way to get things done without sharing passwords or losing track.
Additionally, there are several new moderation tools to make managing your forum easier and faster. For example, you can now use canned responses in forums and use streamlined options to make moderating forum posts easier. And if you are on the go, you can browse and moderate your groups with our mobile website.

You can learn more about the new Google Groups in the help center.
