Question: Am I correct in assuming the above "o"s and "!" pattern suggest network latency, or is there something else I should investigate?

Thank you.

Cannot say what's the actual cause of that kind of output is, but looks unusual enough that further investigation might be worthwhile.

(Or from the movie Young Frankenstein)

Dr. Frederick Frankenstein: Now... that brain that you gave me... was it Hans Delbruck's?
Igor: [Crosses arms] No.

Dr. Frederick Frankenstein: [Holds up hand] Ah. Good. Uh... would you mind telling me... whose brain... I did put in?

Igor: And you won't be angry?

Dr. Frederick Frankenstein: I will not be angry.

Igor: Abby...someone.

Dr. Frederick Frankenstein: Abby someone? Abby who?

Igor: Abby Normal.

Dr. Frederick Frankenstein: Abby Normal?

Igor: I'm almost sure that was the name. [Chuckles]

Dr. Frederick Frankenstein: Are you saying... that I put an abnormal brain... into a 7 and a half foot long... 54- inch wide... [Grabs Igor by throat] Gorilla!? [Strangling Igor]Is that what you're telling me?!
