I made a change to this question's title today because it clearly asked a question that was different to the actual question the OP asked in the (more expansive and specific) body of their question.
My reasoning for doing this was as follows: —
- The OP was clearly asking for a term to specifically apply to 'servers' that are functioning 24/7.
- If the title was left as is, anyone that finds the question in future would be mislead to thinking that the majority of the answers (that answered the question asked by the OP in the body of their question) applied to the more general case, asked in the title of the question.
- The intended meaning of the OP was overtly clear from the body of their question such that there could be no doubt that they had actually asked one question, but titled their question as if asking another far broader question.
Here are the specifics:
The original question title was:
what does it call in English?
The original body of the question was:
If we have some critical servers that have to be running 7 days a week, 24 hours a day and they can't be down even for one second. What does this particular of servers call in English?
Do 'productive' term suit?
This title was later improved, by JonMark Perry to:
what is another word for 24/7 in English?
and the body was further improved to:
If we have some critical servers that have to be running 7 days a week, 24 hours a day and they can't be down even for one second. What is this particular type of server called in English?
Does 'productive' term suit?
However the title is clearly asking a different question to the body of the question still, although it does at least now make some sense.
As such I changed the title further to:
What is another word for a server that is functioning 24/7?
The edit is an improvement to the title in my opinion because the question clearly asks for a word or phrase to describe "critical servers that have to be running 7 days a week, 24 hours a day and they can't be down even for one second. What is this particular type of server called in English?"
Now no doubt the question title can be further improved (I left 'word' in the revised title, which JonMark Perry added when he made the nonsense original title make sense). The OP didn't specify he was looking for a single word originally, so the title could be further improved to: 'what is the term' etc.
Is it correct to alter the title of a question when the question asked in the title is different to the question asked in the body of the question itself, in such examples as this, when the OP clearly meant to ask the question in the body and not the title?
I ask because Mari-Lou A answered the original title quite well and we got into a discussion about the correctness of fixing titles after the question has already received views. I would like the benefit of peer review here! As I see this as clear cut, but in case I am out on a limb, I'll avoid making such edits in future.
