Parts of the internet keep on disappearing on me

[Steve G.]

I sometimes observe something similar, and my feeling it has to do with the
DNS of my provider. I try to reach a place and it hangs. Then if I run a
terminal program that gets me the ip address, there is no problem. Ditto if
I reload the page.

I think - no proof - that my provider's DNS is too slow to respond, or does
not respond at all, and the browser times out after a specified period,
leading to this phenomena. If I try again, and I am lucky, it's fine. If
there is lower load on the DNS, fine too. So this is more common Fridays
(in Costa Rica), and I am not sure if the fault is with the server or the
routing to/from it.
