Comcast outage near datacenter

Frank Phillips No Comments

Update: The service disruption started at about 1:00 pm EST and resolved at about 2:00 pm EST.
The practical impact of this in most cases was that if a Comcast subscriber attempted to access web interface using HTTPS that attempt was likely to fail.

As far as we can tell, this issue did not impact any unencrypted protocols like HTTP or SMTP, so most outgoing emails and incoming clicks/opens were unaffected.

The problem was resolved on its own.

Comcast users may have intermittent difficulty in accessing the Inboxfirst web interface due to a localized Comcast outage near the data center.

High Rate of Bounces at Microsoft Accounts

James No Comments

Update – Deliverability has made progress with the Microsoft team. Bounces are coming down. The initial find is the Microsoft spam algorithm incorrectly flagged IP addresses as “spammy” due to the mail stream increases beyond the threshold’s limits. We will continue to mitigate with them until all mail is flowing freely again.

Investigating – We are suddenly seeing high bounce rates coming from Microsoft accounts (,,, tonight. Our deliverability team is currently in communication with Microsoft to determine the cause of this.
