However, if your server policy denies access to most or all external IP addresses and websites, you'll find steps below on configuring your company's firewall and mail servers. This is to ensure your users can receive PeakLoad breaking news emails and digests, as well as our site.
While our servers are hosted on Vercel.com, PeakLoad's update emails are triggered through Sendgrid.
