Tumblr has had a rough afternoon. The site went down for a few minutes Wednesday afternoon, and while a few pages have appeared to return, most of the site is still down for the count.

Tumblr acknowledged the issue when it began with a tweet from its official Twitter account.

Tumblr suffered a several-hour outage on October 26th. The company attributed that outage to a problem with its uplink servers.

One of the most frequently visited sites on the web, Tumblr recently announced it has reached 20 billion monthly pageviews, a number it credited in part to the growing smartphone market.

UPDATE: At 6pm ET/3pm PT Wednesday Tumblr tweeted that it has taken the site down in order to resolve a network issue.
