Internet problems for some Comcast users Feb 19 2015 (resolved)
2:16 PM Pacific time: We’re receiving scattered reports that some Comcast users, particularly in the San Francisco Bay Area, are unable to reach some sites on our servers (but others are fine).
This appears to be a general Comcast problem; there are many similar reports on Twitter unrelated to us.
Update: The problems were resolved by Comcast at 4:23 PM Pacific time, according to several Internet reports and our own testing.
