You are looking at a mirror server. Those are always a bit behind; they usually receive updates once an hour, but further delays can happen. In this case, you see from the main page that it is nine days behind:
Last replication packet received at 2016-11-08 15:00 UTC
That is the timestamp corresponding to replication packet 99847. The following packet had been lost and wasn’t restored before today.
The mirror server should now be able to catch up, so I’m not sure why it doesn’t; it may fetch replication packets only once a day or so, or its administrator may have disabled it altogether.
