We've been experiencing consistent 403 errors (rate limit exceeded) since August 15th, despite consuming only 10% of our daily API quota. Our usage graph shows an inexplicable spike of 100x our normal traffic, resulting in both daily and 15-minute limit breaches. We've paused all API requests, but the graph continues to display high usage.

An attached screenshot illustrates the anomalous activity. We suspect a potential DDoS attack is artificially inflating our usage. Has anyone else encountered similar issues? Any guidance or support would be greatly appreciated.
