Due to the Dyn DDoS, our subscriptions platform, PubNub, is currently experiencing service issues. Their status page (http://status.pubnub.com/) states, "We continue to closely monitor the DNS resolution issues which continues to have an intermittent effect on internet traffic for many internet services. We continue to work with our DNS providers to work towards resolution."
During this time:
* subscription notifications will be slow and may time out.
* this affects both production and sandbox environments
A temporary workaround solution during this time is to avoid using DNS for affected addresses by hard coding IP addresses for the affected hostnames. To do this for PubNub, use 220.127.116.11 for pubsub.pubnub.com.
Update: This issue has been resolved.
