Just a quick post from the phone, it appears that Omantel have been experiencing a global issue with its ADSL network. I don't know where it's not working but can confirm it's not working in either Ghubra or MQ so far. The outage started around 4am this morning.
No update from Omantel yet on a time frame to get things back to normal.
Do you have Omantel Adsl? Is it working for you? Or not!? Where abouts are you, I wonder if this is affecting all of their subscribers or just people in certain areas.
