One particular webpage and its related webpages will not open

[crazycoconut]

My internet is working fine except for any webpage related to my university. The university's webpage is www.bond.edu.au and any pages related to this URL will not open, including the online blackboard (http://ilearn.bond.edu.au/) and student email (https://webmail.bond.edu.au/ ). However, a few days ago my internet would not work at all EXCEPT for these pages. Then it started working for all pages EXCEPT these. What's the deal?? I tried flushing my DNS cache and that didn't work, and I also tried to edit my 'hosts' file in the system32\drivers\etc folder but I couldn't figure out how to edit it (it wouldn't allow me to) and I don't even know if that would work, I was just trying out what some websites suggested. I have a Dell Inspiron laptop, Windows 7 and to be honest I'm not sure what kind of internet I have... I live in a resort/hotel kind of place and the Ethernet cable just hooks straight up to the wall, no modem or anything. The provider is Allegro and normally I would contact them but they're almost impossible to get hold of... please help me, I really need to access my university's website...

The first thought would always be using another browser for those websites. Second would be running a speedtest of your wired internet connection to atleast give an approximate output and then asking hotel office staff about the particular. Try clearing browser cache or temp files.

Thank you for the suggestions. I've tried using Firefox and IE, neither will load this one webpage. The speed of my internet is doing fine, I did a speed test earlier. I also have cleared my browsing history and cache... I guess all that there is left to do is contact the hotel internet provider, even if it's the biggest pain in the *censored*... alas...
