Having a few problems here

[Marshall Bennett]

Can't seem to get on several websites this morning. This one is slow. What's strange is perhaps 75% of the sites I try work fine. Ran a speed test and all is normal there. A few sites won't come up at all. Tried Firefox and get same results with same sites. Any ideas?
Haven't removed cover on tower and blown out dust in maybe a year. Would that have any effect on this? Thanks everyone!!

Sounds like a problem downstream from you

Don't sweat it for a day and see what happens.

There ways to trace what's between you and the bad sites, but you don't need to get into that. If 75 % are working fine, it's probably not you

Thank you Ralph. I've noticed a marked improvement with Firefox on this site. I'll wait and see what happens. I've noticed waiting is usually the best remedy with a lot of issues anyway.
