The team should have had their two acclimatisation nights in Dingboche, and according to their itinerary, should now be spending the night in Lobuche. Given there isn't a blog update, again we can assume there is no Wifi. If all has gone to plan, they will move on to Gorek Shep tomorrow.
Normally there is a strong mobile signal at Gorek Shep due to a communication antenna being present. This antenna acts as a means to provide communication in the event of an emergency for those trekking to, or climbing Everest.
Having been at Gorek Shep recently on my trip (4 weeks ago), this Antenna wasn't working at the time. If we have had no update by 7pm tomorrow, I will assume the tower is still not working and we may not hear from them for a couple more days when they are on their way back down.
I suggest you check the blog tomorrow afternoon and I'm sure once David gets service he will post an update.
