Ever since Sunday morning, Internet in Bhutan has been patchy. International websites either load very slowly, or do not load at all.
I could not find any updates by DrukNet on their website (www.druknet.bt) or their Facebook page. And the most recent tweet by @bhutan_telecom is "Missed Call Alert is soon gonna be launched........good news for customers...".
So what's happening here? One can only guess. There are currently two international gateways from Bhutan: P/Ling and Gelephu. According to my cursory examination, the Gelephu gateway has been displaying erratic behavior starting yesterday, but for some reason traffic was kept being routed to both gateways. Destinations that were routed via P/ling (e.g., twitter.com) were doing much better than those routed via P/Ling (e.g., google.com).
At around 9:10 this morning (Monday) all traffic started flowing via P/ling, so hiccups should be less frequent. On the other hand, it means increased load on the only operational gateway.
