Route flapping for some subscribers

This evening at about 9:45PM, in attempting to filter out some malicious traffic attempting to enter our network, I employed a series of route filters that caused routes to flap between our network and those of two of our transit providers.  Unfortunately one of those route filters contained a typo.  The typo has been fixed, but it may take another 30 minutes or so for the effects of my typo to settle.
Thanks for your understanding.
