Greetings, All!
This can be considered "working by design", but it really imposes some serious
restrictions on interoperability with Cygwin, that I think can be avoided.
...
After some further testing, this seems to be affecting IP-based UNC paths
only.
The essence is this:
$ dir "\\192.168.1.5\wwwroot\ccenter\bin\online.sh"
26.10.2018 18:16 431 online.sh
$ cygpath -u \\192.168.1.5\wwwroot\ccenter\bin\online.sh
//192.168.1.5/wwwroot/ccenter/bin/online.sh
$ cygpath -u "\\192.168.1.5\wwwroot\ccenter\bin\online.sh"
/192.168.1.5/wwwroot/ccenter/bin/online.sh
$ cygpath -u \\HOSTING64.DARKDRAGON.LAN\wwwroot\ccenter\bin\online.sh
//HOSTING64.DARKDRAGON.LAN/wwwroot/ccenter/bin/online.sh
$ cygpath -u "\\HOSTING64.DARKDRAGON.LAN\wwwroot\ccenter\bin\online.sh"
//HOSTING64.DARKDRAGON.LAN/wwwroot/ccenter/bin/online.sh

This shows that it's not cygpath. It's the quoting, thus the shell
mangles the path.

But cygpath never sees the quotes, so whatever is done to the path that
it gets is actually the work of your shell. In other words, you need to
shell-quote the backslashes as appropriate for your shell.

Not completely the shell.
From a Windows command prompt:
c:\Apps\cygwin64\bin\cygpath.exe -u \\123.456.789.321\wwwroot\ccenter\bin\online.sh
//123.456.789.321/wwwroot/ccenter/bin/online.sh
c:\Apps\cygwin64\bin\cygpath.exe -u "\\123.456.789.321\wwwroot\ccenter\bin\online.sh"
/cygdrive/c/123.456.789.321/wwwroot/ccenter/bin/online.sh
c:\Apps\cygwin64\bin\cygpath.exe -u "\\\123.456.789.321\wwwroot\ccenter\bin\online.sh"
//123.456.789.321/wwwroot/ccenter/bin/online.sh
c:\Apps\cygwin64\bin\cygpath.exe -u "\\\\123.456.789.321\wwwroot\ccenter\bin\online.sh"
//123.456.789.321/wwwroot/ccenter/bin/online.sh
Looks like cygpath is doing something different when the argument is enclosed in quotes (same behavior if single-quote ' is used).

Using echo is a good way of checking just what the shell is handing to
your program. But I totally agree that this is a major interoperability
annoyance.
I'm using Bash 4.4.12(3):
$ echo \\192.168.1.5\wwwroot\ccenter\bin\online.sh
\192.168.1.5wwwrootccenterbinonline.sh
$ echo "\\192.168.1.5\wwwroot\ccenter\bin\online.sh"
\192.168.1.5\wwwroot\ccenter\bin\online.sh
$ echo '\\192.168.1.5\wwwroot\ccenter\bin\online.sh'
\\192.168.1.5\wwwroot\ccenter\bin\online.sh
$ echo \\foo\wwwroot\ccenter\bin\online.sh
\foowwwrootccenterbinonline.sh
$ echo "\\foo\wwwroot\ccenter\bin\online.sh"
\foo\wwwroot\ccenter\bin\online.sh
$ echo '\\foo\wwwroot\ccenter\bin\online.sh'
\\foo\wwwroot\ccenter\bin\online.sh
read -r is an alternate way of getting text into a command line that
might otherwise turn into quoting hell.
$ read -r; cygpath -u $REPLY
\\192.168.1.5\wwwroot\ccenter\bin\online.sh
//192.168.1.5/wwwroot/ccenter/bin/online.sh

Oh, sorry, stupid habit of mine.
Yes, in Windows convention, shell (CMD) does not perform unquoting.
This makes it impossible to reliable pass parameters to cygpath.
