I checked, numerous people have reported them. I received this from them on

"However we are very mindful that this might cause some disruption and we
have excluded the following addresses submitted from further performance

This change will take effect within the next 24 hours. If there are any
other destinations you administer that you wish to exclude please provide
us with the explicit IP address for each such server."
