For about 15 minutes Tuesday night, Dorsey was cut off from Twitter and his 1.42 million followers. Dorsey was Twitter's first user back in 2006. In a tweet referencing the internal mistake, he referenced his now infamous first tweet, which spelled "Twitter" as "Twttr".
Dorsey wrote: "just setting up my twttr…again (account suspension was an internal mistake)"
Although it remains unclear what exactly happened to the CEO's account, the company is just chalking it up to an "internal" issue.
