Please bare in mind that virtually all forms of communication have been down throughout most of Nepal. Our satellite internet connection was only reestablished in the mountains late on the evening of the 27th April and cell coverage has been almost non existent. We are told that there is very little electricity in Kathmandu, so charging phones and laptops will be difficult and will further hinder communication.
