Scheduled
In order to increase the stability and scalability of our core systems, our Midwest data center will undergo SCHEDULED MAINTENANCE Sunday, April 24th from 9PM to 1AM MDT. SMTP and API mail sends will be routed through our West Coast data center so mail will still flow during this time. You may see TCP connections on your server timeout then automatically reconnect for mail send and other API calls. While unlikely, you may also experience the following for a 5-10 minute window:

- Legacy Newsletter sending delayed
- Legacy Newsletter site down
- Legacy Newsletter APIs down
- Marketing Campaigns sending delayed
- Marketing Campaigns site down
- Marketing Campaigns APIs down
- v3 APIs down (mail send will not be impacted)
- Sendgrid.com and account login down
- Free and Paid Signups down
- Recipient unsubscribes down
