Dear all
I am a beginner student. And I have another question. I realized that  there is a line on the website that says
  • THREDDS servers update/restart daily between 2:00 AM - 3:00 AM, and 12:00 PM - 1:00 PM EST/EDT.
    ** Please avoid requesting data during this maintenance window, else you are likely to get an error **
I find that part of my data was downloaded during that time. I want to know what happens if I download data during that time and I'd like to know what this 'error' refers to. Does it mean I can't link to the server? This problem is torturing me, please help me!
Thank you in advance!

I'm sorry I inquired about this because of my negligence regarding Daylight Saving Time. I would greatly appreciate it if an administrator would respond to my question!

What errors did you get when making queries during these (maintenance)
windows of time?

Query errors can occur in datasets that are *updating* (containing new
data) which requires a server restart. If you are querying static
datasets (e.g., the GOFS reanalysis), these datasets will be the same
after restarts.

I managed to download some of the data during this (maintenance)  time, and I'm concerned about whether or not this is the right data. And I always downloaded data from GOFS 3.1's Hindcast data.

I apologize for not being more descriptive.   I always downloaded data from GOFS 3.1's  analysis Hindcast data.

Dear Michael.
One of my biggest concerns is whether or not this the ' Query errors' would cause me to download data from time point 1 when I want to download data from time point 2 instead. This worry is killing me.

Dan,
Please follow the forum rules and provide the missing details to help
answer your question.

THREDDS/OPENDAP is a very simple service. If you ask for data then
data is (typically) returned. If you get a query *error* then *no
data* should be returned. So if you have data, your query was highly
likely successful (whatever this might have been).
