It's looking likely that KrebsOnSecurity will be offline for a while. Akamai's kicking me off their network tonight.— briankrebs (@briankrebs) September 22, 2016
Krebs notes that he was using Akamai's service for free, so he "can't really fault" them for their decision. He added on Twitter, "I likely cost them a ton of money today." While its unclear when KrebsOnSecurity will be back online, you can still access the site's archives via the Internet Archive.
