your email address starts with an A...

So one of Jim's subtle hints here is that for folks willing to pay for
alerting, they(renesys) can (not that I have any data to support this)
alert 'in a timely fashion'.

I suspect when your depending upon a machine under someone's desk
that's not getting revenue support you get what you pay for. Note
well, that I (personally) don't subscribe to any of these services...

I thought that may be the case as well. Do people know of other services like BGPMon that may be able to keep up with 
the load better? Does anyone know how cyclops faired this morning with the additional load?

Usually I get alerts from BGPMon within about 20 minutes of an event being detected.  Not so much with the event this 
morning.  I'm guessing that the orgination of 86,747 prefixes from the wrong AS probably got their MTA pretty busy...

Does anyone know why it takes BGPMon so long to send out an email. It looks like it BGPMon detected the AS9035 
announcements at the right time (around 7:00 UTC) but I didn't get a notification until around 13:00 UTC. It seems 
like many people rely on BGPMon to do this type of detection, so the long delay is frustrating.

Thanks
