Update on Performance Issues

Last Thursday, we posted on this blog explaining any recent service snags in the previous few days.

Since then, we’ve done a number of things to pin down and address the issue. It turns out that the issue was due to our Nginx load balancing server hitting the bandwidth cap as configured. Let me explain briefly:

Our load balancing server is like a traffic cop directing traffic to the right roads. In this example, the roads are the web servers handling Disqus usage. The issue I described earlier is as if the traffic cop just passing out (he has an abnormal heart rhythm). With the traffic cop incapacitated, the traffic doesn’t know where to go even if there is plenty of room on the roads. You’ll have to stretch your imagination to accept such dumb drivers, but I hope that paints a decent picture.

In addition to addressing this, we are constantly adding capacity and rewriting parts of the service to better handle the growth.

On the subject of improving Reactions, which was mentioned in the previous blog post, you will be able to see the improved results of our changes within the next couple days.

  • Nice its working great with me...

    I'm unable to post a comment on my newspaper site. I keep getting a message that I must be logged in to post but I'm already logged in to Disqus. Just this endless loop here. This is my first time using Disqus and will likely be my last.

    Thanks, you are changing into better strategies. I hope it'll give me benefits at later stage.
  • All is good. Thanks
  • Good to hear that you are doing some enhancements with your system and services. Looking forward for the improved results.

    I want to know that what we we install my plugin. http://www.autopartsfair.com
  • I posted this on the earlier problems thread, so I'll cut and paste it here...

    I just noticed that Disqus seems to work fine if I post blog entries from my iPhone or Live Writer (from the PC), but if I post using the blogger entry form on the blogger.com web site, disqus isn't working.

    I just used Blogpress on the iPhone to edit a post I made earlier on the blogger website. After making no edits whatsoever and reposting it using the Blogpress on the iPhone, now Disqus is showing up. I'll try it on another.

    Yup. I did that for all the entries I did this week, and that fixed the comment box not showing up problem.

    So, must be something about posting from blogger.com that disables Disqus.
  • I click to comment on a post it show me this error stating that it couldn't find page.
  • Hey, the comments suddenly have seemed to stop working and folks have been letting me know that they can't comment on my site. But some of the older comment threads allow comments.

    What's up?

  • Me, too. My tumblr gets the same message.

    I want to post a comment on Slope of Hope. Disqus won't let me. I am logged in.

    When I go to post I get a message that my "Comment awaiting approval by a moderator
    Thanks for posting. You must complete verifying your Disqus Profile email in order for your comment to appear here."

    When I click on the "verifying" link I get forwarded to this :
    Verify your email address.
    Some sites require you to verify your email address before leaving a comment. Verifying your email address means proving that you really own the email address that you signed up with. This creates more accountability which reduces the number of unwelcome comments on those sites.

    I do all that. I have verified my email address and password etc. I have asked for the "verification email" multiple times over multiple days. I never received the email.

    I'm stuck not being able to comment on Slope of Hope.

    Please help. Thank you.
    Click the button to request a verification email. If you requested an email but it is not arriving, make sure you set the right address in your account settings.

    Ok I just installed the disqus joomla plugin on my website a few hours ago and everytime I click to comment on a post it show me this error stating that it couldn't find page. I had to refresh each page a couple of time to get the comment box. I'm assuming this is the same problem people have been encounteering. My website is http://edsonandre.com. Can you please help me?

    Daniel, some of the more popular blogs are starting to get hit with troll attacks. The purpose of these trolls is to spam links in the comments to drive traffic to websites that drop viruses or trojans on visitors' PCs. Some sites have turned on the Disqus feature so that only Registered Disqus accounts can post, but this is not foolproof because the trolls can still create multiple fake ID's.

    I was wondering if you have any plans to address this.
