Those 5000 correctables from the log is indicative of noise problems on the line, outside of the residence.
Contact TWC tech support and give them this information.
5000 correctables can be a drop in the bucket.
The number of correctables/uncorrectables should ALWAYS be compared against the number of unerrored or total codewords.
Often you'll find the percentage of correctables/uncorrectables to be some minuscule percentage of the total codewords received, in which case it's nothing to worry about.--
If it's important, back it up... twice. Even 99.999% availability isn't enough sometimes.
