I have pressureNET running on EC2 in US-East. It's collecting data about Sandy from a bunch of Android users in the region, and I only realized a few hours ago that...it's gonna get hit by Sandy. I'm not sure what to do. The Android app has a hardcoded server URL to the DNS of my instance. If the server goes down, and I prepare a backup, all my users will still be sending to the old, dead server (assuming Sandy takes out AWS in that region). So I can also update the app and give it a new server url. But I'm going to lose many hours of valuable hurricane data as users take time to get the update, etc. Does anyone have any thoughts on how I can handle this? I realize my mistakes and know how to fix them for next time, and my current data is obviously backed up. But for incoming data...am I screwed? Edit: I have an idea. I'll update the app and give it a backup URL to use only if the main one is non-responsive. Then I'll publish the update and cross my fingers.
