Donna if you're having problems accessing all sites, probably some major routers that serve your area are affected. since there is bad weather in various states, this may be the case with others too.

routers are computers that act as "intermediate messengers" between you and the sites you are trying to "talk" to. data does not go directly from your machine to the destination sites, but makes many "hops" through various "nodes" or routers. when there is bad weather there may be brownouts or blackouts that can cause routers to shutdown. usually they are brought up again fairly quickly, but while they are down, the internet is set up so that your data will go through a different route, if one is available, but it may be a longer one (more "hops") and so you may experience slowness. even if it is not a longer route, if one machine is "doing the work of two" it takes longer... hence, delays.

when conditions are bad enough to take out a lot of key routers, or, if you are in a smaller town whose internet traffic necessarily goes through one or two specific routers and those get hit, then you can even end up with intermittent failure to access most of the internet. that is even if yours and your provider's computers are fine.
