These custom built solutions are more expensive and cannot be tested at connectathons. This results in are more expensive and cannot be tested at connectathons. This results in higher cost for all countries, who must pay for a one-of-a-kind solution and higher cost for all countries, who must pay for a one-of-a-kind solution and less reliable solutions, since they cannot be tested a connectathons.less reliable solutions, since they cannot be tested a connectathons.
