Yesterday evening we were performing some (scheduled) maintenance on our end.

Exact time-stamp: between 2015/11/05 15:05 GMT and 2015/11/05 18:50 GMT.

For some reason couple of email alerts from Site24x7 didn't make it to our mailboxes, through our MS-Exchange farm!

From our logs I can see a possible negotiation issue.

The maintenance window was properly monitored, as I can see on the Site24x7 reports, though.

We are using Site24x7 for more than a year now and this is the first time that we didn't receive an alert.

That is why I just wanted to let you know, in case it is not only me.

We are looking at a possible issue on our end as well.

Regards,
