What do you mean? This is clearly fiction. The person in the story is dying, the author hasn't died.

Or do you mean whether the person in the story actually died? Yes, he did. He's not typing, these are meant to be his thoughts. He's "stretching" the minute of his death; the story makes an analogy with the no-man's minute of the bug he was trying to debug:

> Tanya used to say I was always somewhere other than here. Now it's true. Only I still don't know where. Sometimes I think it's in that very minute. The server thinks I've been sent. The warehouse thinks I haven't been received yet. And both are right, each by its own clock.

He's been "sent" (to the afterlife) by this plane of existence (the server), but the warehouse (the afterlife) still hasn't received the message, hence "the minute". He's living in that eternal minute, Owl Creek style.
