Webpage not available

Today while i was on my phone checking on my airlines, for a minute or two i had no problem using it and all of the sudden, i couldn't load the site at all. I thought it was the internet, but all the other sites worked perfectly. I even restarted the phone, again the same thing.
When i came home, the same thing on my PC, Google Chrome. This just makes it impossible to play. I emptied the cache, cleared cookies and nothing. The difference is that on my PC after few minutes i can reload it again, but a when i click somewhere, same thing again. It took me ten minutes to load this page to write it, and who knows how much will it take to post it
The message says that the webpage is not available.
Any kind of help would be appreciated, so thank you in advance
