Yes. A way to mitigate the risk of a catastrophic event and single points of failure is to intertwine competing platforms within it. This means if you are sending a vote over the Internet, have it go to not only one cloud routing centre before it gets to the official site, but also send a mirrored, exact duplicate to the competing next company that is fighting with the first company for revenue. Have them receive it and perhaps hold it or even transmit it or let it be viewable to the receiving side, and if they don't match, you have problems. They should match.
Neither one of these companies wants to be known as the company that was compromised and votes were changed. They have a defined interest and a competitive interest in being correct, accurate and as ethical and well-regarded as possible, because otherwise the competitor is going to eat their lunch.
