My extremely un-scientific reply: I make a lot of connections from Washington State to Virginia every day.
Around 5 PM PDT yesterday, I got booted and had trouble re-connecting for about 10 minutes. I figured it was just me, but then a handful of sites wouldn't load for me while others had no trouble. I started to do some traceroutes and they all succeeded, then I noticed my connections to Virginia were restored. I don't think it lasted for more than 10 minutes whatever it was. -A On Tue, May 1, 2018 at 6:31 AM Mike Hammett <na...@ics-il.net> wrote: > This is going to be extremely scientific. </sarcasm> > > Did anyone else see "weird" stuff going on about 10 hours ago, about 6 PM > Central on April 30th?
