Tagadab had a network issue today. Details are on the status page of the website:
http://www.tagadab.com/uk/servicestatus
In short, the primary connection failed and we moved automatically to a secondary link. The secondary link had a packet loss problem which we did not know about because we never use it.
The primary link was restored and the packet loss problem on the secondary link was solved shortly afterwards. The total time was about 2 hours starting from 13:25 this afternoon.
My apologies that this problem caused you service to be affected. It's always checking that status page if you see a problem.
