Update
Messages containing URL links, images, or attachments (including newsletters and report emails) may not send successfully or may not be viewable by recipients. Chats may take longer than normal or fail to send. Core messaging remains operational, but these may be intermittently impacted while mitigation is in progress for DDoS attacks.

Identified
Our underlying provider for mass notifications (email, text, phone, and chat) is currently experiencing a Distributed Denial of Service (DDoS) attack. This attack is leveraging a high volume of rotating IP addresses to generate excessive traffic against publicly accessible resources.
We're in active communication with them as their engineering and security teams work to mitigate the impact.
