[twitter-dev] Getting server 500 errors starting on 1/25/2010 using show api

[Jeffrey Greenberg]

Since 2010-01-25 23:19:02   GMT we are seeing 500 server errors which
we haven't seen in a long while. Using the http://twitter.com/users/show.xml
api...  Not on every call though... seems as if some server in your
array/chain is choking somehow?
