A mention isn't even necessary. Imagine being Light getting his source of information from the internet, his ISP has a small incident with a lightning storm and they lose connectivity completely for a few days while things get sorted out. Involuntarily information has just been leaked irregardless of all other protections, the deaths of criminals would have been disrupted. In this situation you would ideally be working to some great latency of days or weak to give a buffer of information. It's talked about in the first few episodes that he works ahead in case of sickness, but it's not mentioned after that, possibly because it means he can't use those events as cover for on the spot murders (which would stand out from week old information based murders).
Maybe it would have made sense to only use week-old information to begin with.
Probably would have been a better idea. Only later in the Anime does he actually need to do things quickly, all the rest really could have waited weeks or even months. That said it wouldn't have made for very interesting watching if he managed to have that much forward thinking all the time.
Well, being a keyboard warrior is easy. ;)
