Hi folks,
We believe that we have identified an issue which likely causing problems with applications connecting to external data sources. This past July, we announced that we would be adding additional outgoing IP addresses to our service. These IP addresses became active yesterday as part of our routine maintenance. If your application is connecting to an external data source that restricts access by IP address, you are likely affected by this change and you will need to update your firewalls and/or whitelists to include the new IP addresses. Please take a look at this support article for more information about allowing inbound connections from our service:
I apologize for the inconvenienced this has caused.
