Internet is a lot slower here then we were used to at home. We could all (4 of us) watch youtube, download movies, upload photos, whatever, at the same time. Now, during 'rush hour' (in the evening and during holidays) it is even impossible to watch one youtube film, or at least you have to push 'pause' a while before you can watch it or else it blocks.
In my husband's office they need fast internet, and they have experienced that they must negotiate every 6 months or so. For example Fibertel sells this speed at that price, everyone changes, and after a few months, the speed is down, then Arnet does the same, everyone changes to Arnet, etc... In the office they have 2 providers, as it is not unusual that one falls out for a while, sometimes just half an hour, but they work on the server in belgium, so no internet, no computer, no work, and, no phone!
I have been asking my Argentine friends if I should change to another provider, and they all said that they won't, they are certain that they will find a solution, and that we won't be without internet... I have also realised that most of my friends (if not all) have Fibertel.
