What’s the first thing you do when you wake up each morning? You grab your iPhone or Android phone, of course, and you check for the latest posts on Twitter. Next, maybe you dig into Reddit to see what happened overnight. Then you hop in the shower and stream some music from Spotify. Except on Friday morning, you had trouble doing any of those things. In fact, you might still be having trouble doing any other those things right now.

Want a quick fix? Turn the Wi-Fi off on your phone and try again using cellular data. An unknown person or group launched a major DDoS attack on a major DNS host in the early hours of the morning, and it’s impacting a number of popular websites and services that people are trying to access through their ISP.

UPDATE 12:15PM ET: Dyn had restored services but now says that a new round of attacks has interrupted service once again.

“Starting at 11:10 UTC on October 21th-Friday 2016 we began monitoring and mitigating a DDoS attack against our Dyn Managed DNS infrastructure,” major DNS host Dyn wrote in a brief post on its website. “Some customers may experience increased DNS query latency and delayed zone propagation during this time. Updates will be posted as information becomes available.”

The issue appears to be impacting users on some ISPs more than others. Time Warner Cable subscribers on the East Coast likely still cannot access Twitter or Reddit, for example. It’s unknown at this time when service will be fully restored or who is responsible for this large-scale DDoS attack.

Gizmodo has a running list of websites that have been reported as being impacted, and here’s the list as of the time of this writing:

  • Twitter
  • Reddit
  • Spotify
  • Esty
  • Box
  • Wix Customer Sites
  • Squarespace Customer Sites
  • Zoho CRM
  • iHeartRadio
