A much more common source of bitflips is from heat. If you run a desktop computer with more than about 32GB of RAM you probably have bitflips from the heat alone- which is part of why DDR5 adds a weaker form of error correction as standard.
Bitflips in network packets are often stuck bits in networking equipment. Replacing the offending equipment tends to be easy, once it's identified. But you can only do so much when you have no control.
