Greg, thank you for addressing publicly the concern Rooty raised.

> I hope this helps! The server we use seems to be reliable overall, and should not be taxed due to high list traffic, subscribe/unsubscribe, spam, etc.

been upgraded in the past year or two? Or how long should messages
take at low points?
