Earlier today, tweet-a-holics, music lovers, and internet users in general were kicked off their favorite websites due to a distributed denial of service attack (DD0S) targeting a large DNS provider.

Dyn, the company directly affected by the attack, hosts Twitter, Spotify, Reddit, Netflix, LinkedIn and many other big name websites. The company promises to maintain high levels of availability and security, suggesting that preparations for DDoS attacks have bee made, which could mean that today’s attack was particular large.

“Starting at 11:10 UTC on October 21th-Friday 2016 we began monitoring and mitigating a DDoS attack against our Dyn Managed DNS infrastructure,” said Dyn in statement to tech news giant Gizmodo. “Some customers may experience increased DNS query latency and delayed zone propagation during this time. Updates will be posted as information becomes available.”

After a long day that left many users frustrated, it appears that all of the affected sites are operating normally now, with spotty hiccups that aren’t nearly as severe as the original attack.

Now that Twitter is back online, feel free to follow us @TechInformus.
