I noticed late last night that I was not getting any real-time updates in Sense and that the usage graphs were always at least 15 minutes behind. I sent a problem within the app this morning and Sense replied within a couple of hours indicating it was fixed. If anyone in the Sense community is interested some details were posted to http://status.sense.com/incidents/n5gqw8rwv299.
To sense I would update the community page here whenever there are known issues as well. I realize this mirrors the status page however for a lot of customers this is the first place we go if we see issues.
