It sure would be nice if datacenter facilities offered an independent NTP
time source as a benefit for hosting with them. It would also be great if
ISPs would offer this on the local network as well for their customers, as
likely they are already have one in several regions.
time.windows.com and time.apple.com are also fine, though I'm not sure
either has published their NTP source, whether it is a device or they are
simply using the same ntp.org pool as many of us.
I've never had a problem with the public NTP sources, but as George said,
"free" may not always be "free."
