Signage point storms?

Chia Farming & Harvesting
1

Not sure if I understand how signage points are supposed to work. I thought they’d be coming roughly every 8-10 seconds. And ok, if the node has trouble keeping up with the network, then some signage points can be seen delayed or even missed. But today I’ve observed a new behaviour, where dozens of signage points come in within a few seconds, even when the previous signage points came in regularly (so they don’t seem to be a bunch of delayed ones). Below is a log from earlier today (times are UTC+1), you can see the points coming regularly, but then at 10:09:48 there are dozens coming in within ~20 seconds, and after that it normalizes again. There’ve been several such “storms” today, according to my logs.

Is anyone else seeing this? Is it something to worry about?

I’ve checked the associated “plots eligible” log lines, and the number of plots passing the filter differs between these bunched-up signage points, so they don’t seem to be multiple copies of the same signage point.

(These logs are from a remote harvester, the full node has similar logs with “new_signage_point from peer”.)

There was a big network disruption yesterday. Not sure if this is some fallout from that.

Yes, it could be related to yesterday’s disruption. Perhaps the network has some catching up to do? Though I wouldn’t expect that to happen in such a “bursty” fashion.

To make it more clear what I’m seeing, I’ve analysed the current log file (starting 04:35 UTC) and plotted how many SPs there are per minute:
