My wife and I both work online and live in Sosua. We have Delancer fiber (20mbps down) as our main internet and then an Altice hub (5mbps down) which works off the cell lines. Delancer goes down for about 10 minutes every day. Currently, our Delancer line has been down since 2:30pm yesterday and told that the fiber line needs to be replaced in some area. Without question you need a backup if you want to work online. It has saved us many times so far.
