Asked my Grandmother who has HSI/DSL in Philadelphia area she said was working all day. I have FiOS also in same area and wasn't down. Probably just something in your area. If still not working then you should call them.
There were some outages related to CenturyLink recently which could have impacted access to wireless customers and websites, depending on where you were or what you were trying to visit. Verizon DSL and FiOS hasn't seen a wide scale outage to my knowledge, and generally the outage sites will show a typical level of noise from day to day.
