In the pubgrid, there are two nodes which seem to fail to respond to queries. Using the "current and pending operations" pages gives incomplete information. This ticket makes specific (reasonably easy) requests for improvements.

servermap update status should show servers that have not yet answered, rather than only the ones that have answered. Now, one sees "sending 12 queries" and typically 10 answers, and then when the operation completes one can still see 10 answers, but the information that two were asked and did not respond is very hard to figure out.
instead of Finished: not yet, add (DELTATIME) so that one can see how far into the operation the current view represents
in 'recent operations', show time to completion for completed operations, and show time so far (italics? bold?) for incomplete operations
be careful to carry the 'mapupdate MODE_CHECK' operation label to the per-operation details page. MODE_CHECK and MODE_READ are very different in terms of waiting for servers that do not answer.
in pages that list servers, perhaps have some way to include the nicknames in addition to the hashes.
