A number of Facebook users found themselves unable to access the social network Monday for a short time, but things are now back to normal, the company said.
The outage started in the early afternoon and lasted, for some, at least an hour. For many, the site was down completely, while others saw only missing images. Subdomains like beta.facebook.com worked correctly, allowing people to access the site even when www.facebook.com would not load.
Frustrated users took to blogs and services like Twitter to vent, also demonstrating the the outage, while fairly short, occurred in a number of countries worldwide.
An unrelated issue caused Gmail and Google Drive to be unavailable this morning, making it something of a rocky day for those who rely heavily on the Web apps.
A Facebook spokesperson issued the following statement to NBC News in an email:
Earlier today we made a change to our DNS infrastructure and that change resulted in some people being temporarily unable to reach the site. We detected and resolved the issue quickly, and we are now back to 100 percent. We apologize for any inconvenience.
DNS is the system by which clients and servers on the Web keep track of each other, and is occasionally the source of short outages like this one. It can also be deliberately disrupted by hackers, but that's not what happened Monday.
