Most people use the internet during the day for work, school, or leisure. But at night, when everyone is home and trying to relax, internet speeds can drop significantly. And it's not just you - Cox Internet has a history of being incredibly slow at night. The unfortunate reality is that many ISPs throttle internet speeds at night in order to manage network congestion. And while this practice isn't entirely new, it's only recently that major companies like Cox have been caught throttling speeds for their customers. If you're wondering why your Cox Internet is so slow at night, it's likely because of bandwidth throttling. And unfortunately, there's not much you can do about it besides switch providers.
