sbl-xbl.spamhaus.org possible false positives

bvj
Has anyone noticed potential false positives linked to sbl-xbl.spamhaus.org today?

I noticed "Rejected: RBL (sbl-xbl.spamhaus.org)" in the SMTP log for legitimate mail originating from yahoo.com and optonline.net. I sent simple test messages from my yahoo.com mail account to the mail server behind the Astaro SMTP security wall; the first message was nailed by the spamhaus RBL flag, the second message sent 15 minutes later passed.

Legitimate mail received yesterday from optonline.net is getting nailed by the spamhaus RBL flag today.

    There appeared to be an outage of pbl.spamhaus.org on 06 November for about five hours.  The same thing seems to have happened yesterday and today.  Here's a picture of my Mail Manager today showing a message resent two minutes later and getting through.

    Here's the reason from the SMTP log: 
    reason="rbl" extra="pbl.spamhaus.org"

    There was nothing in the IPS log or the DNS log.

    Thoughts anyone?

    Cheers - Bob
