HTTP error using ITIS for classification

[IREdwards27]

I and another member in the lab I work in are using the command classification(n, db = 'itis', accepted = TRUE) to fill in taxonomic info for taxa in a database, and on and off through the last few days we've gotten the following error:

Error: Bad Gateway (HTTP 502)

The book asks that HTTP 502 errors be reported to y'all so you can communicate with the data provider, so I wanted to provide details so that can happen. Thank you!

it was probably a temporary error, try it again

[nahuron]

i will echo the original poster issue, as I have had issues with itis specifically. It seems that on mondays AM (EST) the error is almost a guarantee... today being the same. is there anything further we can furnish to get into this?

[zachary-foster]

That error (if it occurs only occasionally) looks like it is an issue with the ITIS server that we are unlikely to be able to address on our side. I just tried classification(129313, db = 'itis') and it worked. Does this happens for solid blocks of time or do specific queries fail while other around the same time succeed?

[nahuron]

i periodically check if my queries with ritis as well as taxize work (mainly using taxize::get_tsn_(). Today, I have checked a number of times, and on this last check, my queries (including trying your classification example) have begun to work but were returning the error prior to 1300 EST. I think it is as you say @zachary-foster , it is probably something on the ITIS server side?

[sckott]

yeah, in my experience, ITIS just has quite a bit of downtime, and that's the way the service is. If its super painful to have these errors, you could try various other ways of querying itis, eg., https://github.com/ropensci/taxizedb/ or https://github.com/ropensci/taxadb or if you are a SQL person just download the database yourself https://www.itis.gov/downloads/index.html

[nahuron]

Thanks for chiming in @sckott as well. I've been putting off getting my feet wet with SQL, but if I can't get through the queries I have left, I may just have to bite the bullet! It may be worth trying to get a schedule of the routine ITIS downtime to tuck in function documentation if it's easy enough to come by.
