Thanks for reporting this problem!

It seems there's a new Onionoo client in town, and it's putting quite
some load on the Onionoo server:

The quick fix was that our sysadmin increased some Apache limits, so
that it can handle more requests in parallel than before.  Apparently,
Tomcat can handle those additional requests just fine.  Thanks, weasel,
for implementing this fix on the weekend!

The better fix will be to make the new Onionoo client a better citizen
by sending fewer requests.  I'm talking to the developer to discuss
possible solutions.  It may take some time for those solutions to be
deployed.

Always fun to write Internet-facing services!

All the best,
Karsten
