I clear cache, but I still see the same thing for a long time, blank or error page.
Hoping my isp is very bad. An online screenshot site saw the same error page, but
not for a long time.

You can use OpenDNS:
208.67.222.222
208.67.220.220


And at any time you can refresh your domain at https://cachecheck.opendns.com

Thanks. It failed every time, because of captcha. I type it correctly, but not accepted..

It would be great if there is a free online service (such as a web site submission service used for crawling purposes) which would trick all dns systems in the world into updating themselves when resolving a given domain.

I use it regularly...
No any problems with captcha.

flush your dns

How?

I also want other people's cache to be flushed.
(other people=endusers invited to the landing page. )

And this "flush" has no any effect on your ISP cache... so use OpenDNS...

"Flushed dns" with this command:

sudo /etc/init.d/nscd restart

and also this one:

sudo /etc/init.d/networking restart

(on linux), no change so far.

Because it is cached on your ISP DNS servers... So local flush is useless.
Switch to OpenDNS your device and then flush/refresh via link above...

What Jurgen said basically.

You cannot control the DNS of others so you'll have to wait a bit for it to propagate globally for everyone.

OpenDNS has 90M users globally...
So when your refresh there - all other OpenDNS users will see your DNS settings instantly...

Wow, opendns worked,.. but only on Chromium. on Firefox still there is a blank page.

(And shamefully, I had to use a proxy, otherwise there is captcha problem as said above.)

It means that Firefox has DNS cache as well...
The best solution - restart your computer...

What are these IP numbers for? Am I supposed to use them anywhere?
IPs of DNS1 and DNS2 servers...
They must be set in your Internet connection settings... or on your router...

check your dns resolvers:
cat /etc/resolv.conf

this should list 2 or more nameservers. change those ips to the ones provided by Jurgen.

Probably, he has NetworkManager on his machine...
Open it... and Edit your Internet connection settings there...

Interesting, so can I hide my IP in this way (and from who)? I was wondering how one could use
such IPs to "change IP". For example Paypal blocked my account because of IP, and I can't use proxies based on web sites because they would steal my pw's, even if they worked. Hiding IP would be good in outbounding as well (when done using their form-mail on their websites).

I just type the web site address for which I'm trying to make dns work correctly. There is no place to add IPs.
You say, on the browser. Is such a change supposed to be permanent? I use direct connection to internet, so my IP becomes visible to sites I visit. Would they then see opendns IP? Is there any security risk in this (do I need to trust opendns)?

Too many questions, because I'm too naive. Any answers would be greatly appreciated in advance.

No, those IPs have no any relations to your IP... Here only VPN or Proxy helps.
They serve as DNS servers instead of your ISP DNS servers.

What is your Linux distro?
Almost all are supplied with NetworkManager by default...
So just open NM, select your default Internet profile... switch to tab with DNS settings... and enter those IPs and save...
And restart your computer.

And if you are connected via router - you may ignore NetworkManager.
Open your router settings, find DNS tab - and set OpenDNS IPs there.

flush your dns

You will need to do this via Terminal (i.e. command line). Additionally empty all history on your browser(s).

Try to check on another browser , restart your modem / conection device, its usually depends on how long TTL (time to live) on DNS configuration
