There are 12 different root server anycast constellations, and they all serve the same root zone data. But do they all serve this data the same way? In particular, when the response size is large do all these root server systems respond in the same manner? This is a report on the different forms of responses that were observed when the root servers were coerced into offering a larger than normal response. To illustrate the differences in behaviour that were observed, the root servers are scored on a six star scale and the report will show the results.
