So today i ran into one more issue with Openstack , the error showed up when i logged in to the dashboard and clicked on Project–>Instances.
What i saw terrified me because is saw “NOTHING” !
A day before i had the same issue and i thought it’s related to RAM so i restarted and everything started and operated normally, but this time the reboot didn’t help.
So i started scratching my head and started wondering what might be the reason. I searched internet but no success. I searched log files but nothing made sense at that time, so i rebooted one more time and an Error appeared saying something like “Openstack glance-registry api error limit reached ” So that gave me a head start that it has something to do with system being low in space.
A df -h showed that / is 100% full. I removed some unnecessary files , rebooted the system and Viola !
So today i had a strange problem when i was only able to access google.com and not other sites. I was able to browse gmail, but not mail ru.

1) Both Firefox and Chrome giving the same problem.
2) I was able to browse with Chrome if Ultrasuf Extension was enabled.
3) Firebug reported “Aborted” in the Net tab
Restarted the System
Changed the IP address Result:
