Your connection problems are usually caused by your internet provider in some cases you will lose connection often , slowly stream videos , terrible download speeds..
alot of the time its due to internet usage limits..
"fair use policy" this is if your using a mobile internet provider like o2 , t-mobile , orange , vodafone ect.
or it could just be a weak signal , try contacting your network administrator (Your Internet Service Provider Company) if this problem is continuous.
Or Move Your Broadband Router/Modem/USB Dongle to another location of your home to see if the signal increases.
If The Problem Is Solved I Would Still Recommend Calling Them Up To See What Might Be Causing This Issue.
Unless of course FlyOrDie servers are having issues which is also aossible but doubtful as FlyOrDie is rarely offline.
If it is FlyOrDie then they will no doubt notify you as soon as they are aware of the issue at hand.
