One reason to monitor your infrastructure is to signal longer outages, or even better review past outages and prevent longer ones.
It is not the reason I created [Archive.is] EmbarcaderoMonitoring (it was to rule out problems between my systems and the Embarcadero sites), but it does help me gain insight in their infrastructure.
In this case, the [Archive.is] Docs – EmbarcaderoMonitoring shows that after months of OK operation, it suddenly started failing, at the same day parts of the other infrastructure also failed. It recovered, just like the other parts, but unlike the other parts, it was now down for almost a day when I took the screenshots:
Hopefully someone at Embarcadero realises the downtime too.
Edit
Indeed: after more than 2 days of down-time, it got sort of fixed: http://docs.embarcadero.com/ works, but https://docs.embarcadero.com/ still fails.
Of course there is still a lot of red at [Archive.is] EmbarcaderoMonitoring, but that has been normal for months:
