Metrics Portal Network graphs show drop due to a parsing bug
The graphs Version, Platform and Bandwidth https://metrics.torproject.org/network.html#versions https://metrics.torproject.org/network.html#platforms https://metrics.torproject.org/network.html#bandwidth
show a significant drop.
It looks like suddenly all relays would have disappeared or the authorities would have been down or overloaded.
On IRC "Sebastian" told me that this happened due to a "bug with parsing descriptors". He also said that the graphs can probably be fixed.
It looks strange and scary, so it should be "fixed" whenever that's possible. Alternatively you might wanna explain it in a blog post.
