Three Months to Scale NewsBlur

49 Comments and 86 Shares

At 4:16pm last Wednesday I got a short and to-the-point email from Nilay Patel at The Verge with only a link that started with the host “googlereader.blogspot.com”. The sudden spike in NewsBlur’s visitors immediately confirmed — Google was shutting down Reader.

Late night at the office

I had been preparing for a black swan event like this for the last four years since I began NewsBlur. With the deprecation of their social features a year ago I knew it was only a matter of time before Google stopped supporting Reader entirely. I did not expect it to come this soon.

As the Storify history of the Reader-o-calypse, NewsBlur suffered a number of hurdles with the onslaught of new subscribers.

A few of my challenges and solutions

I was able to handle the 1,500 users who were using the service everyday, but when 50,000 users hit an uncachable and resource intensive backend, unless you’ve done your homework and load tested the living crap out of your entire stack, there’s going to be trouble brewing. Here’s just a few of the immediate challenges I faced over the past four days:

  • My hosting provider, Reliable Hosting Services, was neither reliable, able to host my increasing demands, or a service I could rely on. I switched to Digital Ocean and immediately got to writing new Fabric scripts so I could deploy a new app/task server by issuing a single command and having it serve requests automatically within 10 minutes of bootstrapping.
  • It didn’t take long to max out my Amazon Simple Email Service (SES) account’s quota of 10,000 emails a day. So a few hours into the melee I switched to Mailgun, which unfortunately resulted in emailing myself 250,000 error reports. If tried to email me and couldn’t get through, it’s because 50,000 emails about lost database connections made their way ahead of you in line.
  • Eventually, I was just plain blacklisted on SES for sending too many emails.
  • Fortunately, when the PayPal fraud department called because of an unprecedented spike in payments, I was prepared.
  • Having HAProxy serve errors (site is down, maintenance, timeouts, etc) with a 200 OK status code instead of the proper 500 Exception status code because of a ridiculous undocumented requirement to include HTTP Headers at the top of the error template. When your webapp uses status codes to determine errors, you get extremely strange behavior when it loads utter crap into your DOM.
  • The inevitable file descriptor limits on Linux means that for every database connection you make, you use up one of the 1,024 file descriptors that are allocated to your process by default. Changing these limits is not only non-trivial, but they don’t tend to stick. This is responsible for bringing down Mongo, PostgreSQL, and the real-time Node servers, all at different times of the night.
  • The support queue is enormous and I’ve had to spend big chunks of my 16 hour days reassuring paying customers that eventually Stripe will forgive me and my unresponsive servers and will send the payment notification that is responsible for automatically upgrading their accounts to premium.

The sad extent of my St. Patrick’s Day

As a one-man-shop it has been humbling to receive the benefit of the doubt from many who have withheld their judgment despite the admittedly slow loadtimes and downtime NewsBlur experienced. Having the support of the amazing NewsBlur community is more than a guy could ask for. The tweets of encouragement, voting NewsBlur up on replacereader.com (If you haven’t yet, please tweet a vote for “#newsblur to #replacereader”), and the many positive comments and blog posts from people who have tried NewsBlur is great.

It has also been a dream come true to receive accolades from the many who are trying NewsBlur for the first time and loving it. Since the announcement, NewsBlur has welcomed 5,000 new premium subscribers and 60,000 new users (from 50,000 users originally).

NewsBlur users are intelligent, kind, and good looking!

The next three months

Over the next three months I’ll be working on:

For those of you who are still trying to decide where to go now that you’re a Reader refugee let me tell you a few of the unique things NewsBlur has to offer:

  1. Radical transparency. NewsBlur is totally open source and will remain that way.
  2. It still feels like RSS, just with a few more bells and whistles. NewsBlur provides actual list of posts, as opposed to the more curated magazine format of some of the other popular replacements. This clean interface makes it easy to see the stories you want. One innovation however is the four different view options you have. NewsBlur can show you the original site, feed, text or story view.
  3. It has training. NewsBlur hides stories you don’t want to read based on tags, keywords, authors, etc. It also highlights stories you want to read, based on the same criteria. This allows you to find the stories you care about, not just the stories that the Hive cares about. And best of all, NewsBlur will show you why stories are either highlighted or hidden by showing the criteria in green or red.
  4. NewsBlur has rebuilt the social community that Google had stripped out of Reader. Users can share stories through their Blurblog and discover new content by following friends’ Blurblogs. The People Have Spoken is the blurblog of popular stories.
  5. Because NewsBlur is entirely open-source, if you don’t want to pay you can host your own server. Instructions are on GitHub, where you can also find the source code for the NewsBlur iPhone + iPad app and Android app.
  6. Most importantly, NewsBlur is not entirely a free app. The immediate benefits of revenue have been very clear over the past few days. Not only are NewsBlur’s interests are aligned with its users, but as more users join NewsBlur, it makes more revenue that can be used to directly support the new users. Not convinced that paid is better than free? Read Pinboard’s Maciej Ceglowski’s essay Don’t Be a Free User.

Shiloh during better times. Your premium subscription goes to both server costs and feeding her

With NewsBlur’s native iOS app and Android app, you can read your news and share it with your friends anywhere. And with the coming improvements over the next three months, you bet NewsBlur will be the #1 choice for Google Reader survivors.

Join NewsBlur for $24/year and discover what RSS should have been.

Heeeey, when you share something you should always comment something so we can reply to you! Newsblur has a, uh, "feature" that makes it so others can't comment on your shares unless you do first. (I'm only telling you this here, because it's the most recent thing you shared that you commented on ^_^)

Also, I think that NewsBlur has pretty much recovered from the Great Reader Exodus.
samuel
2819 days ago
Nope, not even close to recovered. While the servers are stable, the load times are now 9X where they should be. I have charted some remedies, but they're going to take time. And I still have yet to go 24 hours without a server meltdown.

You won me over, I completely ditched google reader and deleted all of the data over there. I need some confirmation on if the price will go back to $12 and when exactly it will do this, I understand why you did it but I was there when it changed and that obviously made me do a double take. I NEED the features of the premium account so please let me know if I should wait or if the price will never go back down.

You're doing a great job, Samuel. When I checked out Newsblur last week, your dedication to building a great service was evident from the get-go. It made signing up for premium an easy choice. Keep up the good work, and don't worry about breaking a few things along the way.

I joined a few days ago and have been very impressed. I'd been wanting an RSS client that would sync between my laptop and iOS devices (and wasn't tied to Google), and NewsBlur delivers on all fronts. Thanks for putting in all the work, Samuel!

Speaking as a Reader refugee, I have been very impressed with NewsBlur so far - so much so that I am starting to wish that Google had shut down Reader sooner. In many ways, NewsBlur strikes me as being everything that Reader could have been.

I live in Europe, so I woke up one morning with NewsBlur already in meltdown mode, and found about Reader a while later, so I just decided to sit out the mayhem and return to my feeds a couple of days later. You handled the situation as best as you could, congratulations and be assured that my premium subscription will be renewed once it ends. I am also glad that I quit Reader away ahead of the announcement of its shutdown and found this service.
