Posting here at request of @Shawhelp
Been having issues intermittently with my connection today, seems like they're related to the DNS server at: nsc1.so.cg.shawcable.net [18.104.22.168].
When my connection is having trouble/connections are lost, the above server will not respond or only partially respond to ping requests, at between 60-80ms when it does.
At the same time, the other DNS: server nsc3.no.cg.shawcable.net [22.214.171.124] will respond fully to all requests at between 10-20ms.
The same is true for a ping to www.google.com (since it's name resolution is cached).
I checked to see if others requesting assistance from @shawhelp were having issues, and the twitter user kidaru symptoms would support the likelihood of an intermittent issue of the same kind.
