No. This was the example that I mentioned with Mongolia, which is the absolute worst case in the globe, in my opinion, for connectivity.
There are three methods. There is the modeming in of the results, and these are all with unofficial results. The official results are the paper ballots. There are also redundant copies of memory in the machines. A copy of the results is modemed in to the central location, if there is a connection. It can be over satellite, broadband, or telephone.
In the cases where it doesn't work for whatever reason, and that happens, they are telephoned in, and that's the same as what we currently see in Canada. The returning officers phone in the results and they are entered into the computer, double-checked and double-called. Sometimes, and we know this happens at Elections Canada, there's a transcription error. That's why it's unofficial.
Then, of course, it's official when you reconcile the ballots with all of the audit logs from the polling location. That happens at some point after the election.
