Hello,

I’m an engineer at AS200020. We indeed had a route leak yesterday between 16:45 and 17:07 UTC.
This was caused by a mistake in the configuration of one of ou core routers by one of our engineers.
We leaked full table to one of our transits, which is apparently accepted. We’ve seen some prefixes from a couple of AS 
numbers coming in. Facebook was not one of these AS’es. As far as I can tell it’s not related at all to the major 
incidents at Facebook.

We are very sorry for any inconvenience people could have experienced.
If you received complaints in the mentioned time period and want to know if it could be related, please let me know.

Best regards,
