[Ops] non-responsive services in the Registry

[Christophe Arviset]

Dear all

Indeed, at the Euro-VO Registry, we’ve recently applied the same rules as Pierre and in all cases, we did not have to go up to point 4 (ask IVOA Exec for final decision), as earlier steps and through step 3 (ask national representative at the IVOA Exec to take decision) was enough to have the confirmation.

Thanks in advance

So I'm looking for information about how to remove services from

the registry that are not responding and whose responsible contacts

aren't either.  Renaud pointed me at a mention on the Ops page

(https://wiki.ivoa.net/twiki/bin/view/IVOA/IvoaOps#Procedure%20for%20Removing%20Non-Respo)

which refers to "A revised procedure was adoped by the IVOA in

October 2016."  But we don't find it.  Anybody know where I can

hear about what other registries are doing and what we should do?



Well... this, I seem to remember, refers to item 7 in these Exec

minutes:

<https://wiki.ivoa.net/internal/IVOA/IvoaRepMin/ivoa-fm66-20161020.pdf><https://wiki.ivoa.net/internal/IVOA/IvoaRepMin/ivoa-fm66-20161020.pdf>.

I think Pierre had a nicely worked-out paper back then that I may

even be able to dig out if necessary.  Pierre, if you have it at

hand, can you perhaps put it on the twiki in some suitable position?



But then in practice here's what I've been doing when I encounter

dead services by chance, typically because dead services have bad

resource records, too:



(1) use the contact address to ask the service's operators



(2) if they are unresponsive, try the originating publishing

registry's operators



(2a) if they are responsive, work with them to either get the service

fixed or have it removed from their publishing registries



(2b) if they are unresponsive, see whether any living services are

published through that registry (in case *it* is still alive).  If

that is the case (never has been), improvise.  Otherwise, ask the

Exec to tell the RofR to remove the dead publishing registry.



Perhaps that's something we should note down on the Twiki, perhaps on

a page linked to by Ops and Registry?



               -- Markus

I will talk about experience in removing ghost service from the registry, our (group of cleaners) where having a step that are more empirical

1) As Markus said, first try to contact the owner of the service, in those case usually nobody answer, because we had already did that many time.

2) try to see in the same institute if you know somebody close to ...
Sometime it worked, mean we have an answer like "it's dead you can remove it"

In that case you go with this answer to the owner of the registry where the service is registered and ask to make it in status='inactive'

3) still no answer, try to find (usually on exec) the national representative in iVOA

sometime it solve the problem, because he know who is now in charge of the service and it can allow to change the resource content or pass it to inactive

4) nothing work, ask exec to take a decision on the status of the resource to remove it from registry



I hope it helped

Regards

Pierre
