This answer links to "NASA's Performance Vehicle Calculator" with the link

I've also found the same link in

But when I try it, all I get is

This site can’t be reached

elvperf.ksc.nasa.gov took too long to respond.

ERR_CONNECTION_TIMED_OUT

So while it does not reject me, I can not access it.

Question: Does this site have any restrictions based on location or otherwise? Is it in fact unavailable in general? Is it intended to be open for public use?

edit: I've done a quick search for ksc.nasa.gov and found several more KSC sites and all of them are unavailable to me, giving the same connection timeout. However, just nasa.gov works fine.

I can access it without problems. There's no requirement to register and log in, that means it's a public website.

  • $\begingroup$ Thanks for the quick feedback. I'll keep an eye on it to see if the response improves. $\endgroup$ – uhoh Apr 20 '18 at 7:37

    $\begingroup$ I had something similar with www.nasa.gov a while ago. Persisted for a few weeks, then went away. Likely a configuration error somewhere in a routing table. $\endgroup$ – Hobbes Apr 20 '18 at 9:23

    $\begingroup$ @uhoh can you try using a VPN that emerges in the US to see if it's a locale restriction? $\endgroup$ – Organic Marble Apr 20 '18 at 13:14

    $\begingroup$ @OrganicMarble I did a quick test of some dtic.mil links in other questions and answers here, including one of my own, and I can't reach those either. I think living in the shadow of a large technology vacuum cleaner across the straight puts me in an unofficial "cone of silence". $\endgroup$ – uhoh Apr 22 '18 at 3:58

    $\begingroup$ @OrganicMarble update: I have had occasional success with both ksc.nasa.gov and dtic.mil in various WiFi locations around town but it's spotty. Just "one of those things" it seems. $\endgroup$ – uhoh May 6 '18 at 2:46
