So someone made a change to put up a new promotion on Tuesday. No big deal, right? The problem is with this new promotion everytime someone read a note on BP they'd get a flash popup. That flash popup was 87k. Just -today- (i.e. in 11 hours) we had over 25g of downloads of that stupid flash file. It increased our peak bandwidth usage by over 15 mbps. That's over 10 t1's worth of data getting pumped out, all that one stupid file.
Here's a fun image of what happened after we found it and took it down:
Note: That's not our total bandwidth, incidentally, just for that one cluster of servers. We push close to 200 mbps at peak.
