We are checking into reports of bad packetloss now.
Services like SMTP (outgoing email) are being impacted most right now, with the packetloss as reverse DNS lookups are failing.

working with upstream NOCs and staff to get blocking going upstream now, it is taking a moment to get them on the line…
