My website is down for just me. tracert
finds the server though it reports a different domain (and at 23 hops seems rather lengthy). ping
works, citing the same IP as tracert. nslookup
also reports the same IP.
Web browsers, ssh and sftp all report "the connection has timed out".
I see same issue from multiple computers (all on same local network though; Windows 7 & 10).
I can connect to the control panel of my host (DreamHost) and access all the usual functions. Nothing is out of order there.
I can browse to the site using Lynx from a shell console on a server I have access to in another country. Webservices such as isup.me and Nibbler report no problem connecting the site.
This has happened a few times over the last couple of months. After half a day or so it works again. How do I narrow down where the actual issue is?
The website is www.yukongis.ca

nslookup -d2 example.com
(replace example.com with your site name).nslookup -d2
output @Twisty. However it might not be helpful as I can connect to the site now. I rebooted the local router (gateway.mkcd in the above). I won't know if that was the likely fix until it goes down again.
