I sometimes use mobile internet (via UMTS in my case), and sometimes the high latency (>200ms) is rather annoying.

I did some googling and found out that latencies of 200-300ms are normal for UMTS. However, I found no explanation why this is the case. To better understand the problem (and to beef up my networking fundamentals), I asked about the reasons for the high latency:

"Why do mobile networks have high latencies?"

However, the question was closed as off-topic both on serverfault.com and on SU.

I'm slightly surprised by this. I figured that as a question about networking technology, this is on-topic on both SF and SU. I initially put it on SF because it's rather "advanced", but re-posted on SU after it was closed, figuring SU is the more "general" site.

So:

• Is there a way to make the question on-topic on SU or SF?
• Or is there another site where it's more appropriate?
• Or is there simply no site for general networking questions (which are not specifically about a home or professional setup)?
• Or is there some other problem with the question?
