For your information, MOST of broadband ISP's they have unofficial limit of downloads. Sure it vary and depends on price of backbone. In lebanon, it is now most expensive in the world, plus because of political situation, they dont give upgrades at any price.

Your connection is still unlimited, but speed is lowered. Such thing called "Fair usage policy". Let's say 100 users, who paid total $4000 (but ISP will get for bandwidth only $10-$15 from it, it means let's say $1200), by lebanese prices it is price of 1 Mbit/s (but theory only, in practice it is more expensive). Means 316/GB month, and because most of people download at day - 158GB. Means 1.5Gb limit for each person. When you take your 12GB, it means some users will expirience worst connection. Unfair. So if you want to get more - pay more.Download penalties and fair usage
Do you use your unlimited broadband connection to download music, movies and high resolution photos? Is your package really unlimited? A recent ICM survey found that 71 per cent of users thought their broadband package was unlimited but 75 per cent of the deals out there actually have limits on how much you can download.
This means that you could end up being charged for persistently exceeding your download limit. Here is what you could end up paying:
Eclipse option 1 – 2GB limit, £1.75 per GB over limit
Pipex Mini 8MB – 2GB limit, £2.70 per GB over limit
Madasafish Max – 5GB limit, £2.00 per GB over limit
“Hidden” download limits also exist in the form of fair usage policies. These are put in place by your ISP to ensure that your downloading doesn’t affect other people’s connections.
In accordance with their fair usage policy, some ISPs, including Virgin and BT, can even upgrade your broadband to a more appropriate and more expensive package, so you will have to pay a higher upfront fee every month.
