It seems that the fiber link problem announced 10 days ago by Bhutan Telecom was fixed: A few days ago I ran a speed test against a server in the U.S. and got a download speed of about 1.7mbps.
On the BT website, I found no announcement regarding the restoration. Looking at previous Bhutan Telecom news, it seems that only breakages are reported. It would also be useful to know when services are restored. An RSS feed for the BT updates would be a useful addition.
