The number in the status message can be anything from 0 to 9, apparently. Based on the information we were able to find after a quick Google search, these identify Facebook's Chat and Messenger servers. When you're on Facebook.com, the site periodically asks those servers something like, "Hey, you still there?" If the servers don't respond quickly enough, Facebook will slow down or stop altogether until it gets an answer.
Many things can keep Facebook's servers from answering quickly. Ad blocking isn't one of them, as far as we know. We couldn't find a single answer that has solved the problem for everyone. Here are the solutions we were able to find:
- Try using Google DNS servers instead of the one your Internet Service Provider gives you. Apparently, the DNS servers used by Charter and Verizon are particularly slow.
- Try turning off video auto-play in Facebook's settings.
- Try using a custom filter to block Facebook's server status check. Note, this will change how Chat and Messenger notify you of new activity. If you try this, please be sure to read the warnings in the post.
- Try resetting Chrome's settings.
- If you have McAfee Site Advisor (it may also be called McAfee Webadvisor), try disabling it. Visit chrome://extensions and clear the "Enabled" check box.
- Try opting out of Facebook's personalized ads.
If you have other solutions that have worked for you, please let us know in the feedback for this article. Thanks!
