Thanks for the technical update, we appreciate the time you take to keep us informed 
I still have some concerns on this testing strategy, primarily the testing on production ! I know you will say you are using the Saltlake Satellite, but as you mention you are testing uploads and that hits nodes which run the production satellites as well - this sort of test in my view should of been done on storj-up or on the QA satellites, it will be concerning for many Enterprise customers to see this, not to mention existing customers - anyway, itās done now.
Your quote implies that we should be expecting some minimum IOPS and Bandwidth requirements for nodes to be defined, and also a change from the geo-ip and ip subnet based node selection ? Sorry if Iāve made the wrong assumption.
I would agree with this, but please update the requirements and TOS for running a node, the message has already been run what you have, however people on enterprise disks and storage systems are naturally going to be better than a rpi3 nodeā¦
we suspect that the problem is largely the storage node network - link
Also, thereās lots of changes in around monitoring Storage nodes, and the disk subsystem monitoring - again if you are going to start doing that outside Monkit, it would be nice to let SNOās know so we can opt in / opt out of this 
this change introduces a mechanism for the satellite to keep track of which nodes successfully received pieces during segment uploads and prefer those nodes during the selection process - link
Again, not complaining, my nodes can take all you can throw at them, as they are tightly rate limited, however I feel sad for new operators, or seasoned veterans who have always followed the āuse what you haveā, and might now find that they are slower then the many Enterprise grade operators in the public network, and for which the node usage might be impacted.
I guess Summary:
-
Please update the Terms of Use, and Node Requirements based on the feedback from this testing, so node operators aware of what specifications they need.
-
If there is going to be any non-anonymous profiling of nodes, and their hardware - this should be an opt in choice.
-
If you are going to change how nodes are selected, outside the /24 IP restriction, then please announce those changes in advance - I know you will get moaning, but is will be better than sudden surprise in my view.
