Given decades of intermittent but destructive human on human fighting and some inherent telecommunications technology problems (population estimated as 32 million; a claim of 23 million cell phone users seems extraordinary) the problem is whether there is any phone coverage in the areas near the epicenter. It is doubtful that there are one million internet users in Afghanistan. Whether civilians, doctors and hospitals needing help or reporting status can communicate with a central agency is not clear. Beyond that, trying to handle the surge in queries by anxious relatives is tough for  internet servers that are also accepting real-time updates of who is dead, alive, injured or missing. It is certainly the case that looking for trapped or inured people is time-sensitive.
