To say that a site is inaccessible is hardly helpful to its administrators. Please help us address the issue head on by using the following tips:

1. Run a traceroute from your commandline and from an independent site.
From the command line of your computer, run on Windows

tracert myportal.upou.edu.ph

on Mac or Linux

traceroute myportal.upou.edu.ph

Please send the whole result to [email protected]

From an independent site like network-tools.com, a traceroute result would look like this

In both cases, both traceroute instances suggest that MyPortal is reachable. In the event that your local traceroute fails but the one from third-party works, please report the issue to your local Internet service provider (ISP).

2. Change your computer's DNS.
It's possible that your local ISP's DNS is acting erratically. Change it to some reliable DNS like Google's (8.8.8.8 or 4.4.4.4) or those (208.67.222.222 or 208.67.220.220) from OpenDNS. 3. Test your site's DNS.
Diagnostic sites like Pingdom can help your administrator figure out the issue. Report if you find anything strange.
