Every election has problems. Most of the time, those problems aren't
noticed. Elections rely on a lot of back-end infrastructure, besides the
actual voting itself.

It could be a DDOS attack, or simply duct-taped systems having trouble
with the load.

Voting early (mail, drop-off, in-person) means more time to fix glitches.

“distributed denial-of-service” attacks, which inundate a computer system
with requests, potentially clogging up servers until the system becomes
inaccessible to legitimate users.
