UPDATE 8:25 p.m. EDT -- Sprint said it has restored service to all states where users reported the inability to make calls or send text messages. The outage lasted more than an hour. Sprint said users in Ohio, Indiana, Illinois and Wisconsin were affected. "We apologize for the inconvenience to our customers," the company said in a statement.

Original story:

Sprint users lit up Twitter Friday afternoon with reports that the network was experiencing massive outages. Users of the service said they could not use their Sprint connections to make calls, send texts or log on to the Internet. 

The outage began at 6:30 pm EDT if not earlier and is still raging on, according to several tweets. The Overland Park, Kansas, wireless provider has yet to publicly address the outage, which is affecting several regions of the country including California, Indiana and Illinois, among other areas.

Unfortunately for tech users, this week has been riddled with spotty service. On Monday, Twitter users had to deal with outage issues on the twitter.com website while Facebook users went through a similar experience Thursday.
