Looks like the archives after 130 EST PM today have been delayed? im having the same issue, I just tried firefox to be save and it gave me an error that "feed had no archives", refreshed and still showing the same as before just through 130.
The archive servers are now recovering and you should see archives start to populate again in the next hour or so.
Our apologies for the outages - we needed to do some emergency maintenance and we made a mistake on bringing up the archive servers after the maintenance that resulted in them not archiving since then.
I'll be monitoring the servers during the day today to make sure they properly recover.
Thanks again for your patience,
