Hello Bloomberg are you there?

Last morning I received number of alarming mails like this one:

I got one mail for each type of rate we fetch from Bloomberg each morning. Bloomberg status code=100 means there is nothing to pick up.
Normally we have the rates on first attempt, so I assumed I messed something up, which I actually do on a regular basis.
After I left the company the first time one of my managers told me “we are very grateful for all things you have done for us,
but the fact is the entire IT landscape have stabilized a lot since you left”. I looked around but could not find
any errors in my rate import job. One of the recipients of the alarm mails sent me a note
“Doesn’t look very reliable your system does it?” But to my great relief just a minute later he relayed a mail from Bloomberg:
Important Data License Alert
Due to technical issues, Per Security and Web Services users may be experiencing delays with some requests.
We are currently working to resolve the issue.
Yes we had noticed that😠

I waited half an hour then copied the line:
./scriptS.php schedule=BG_retrieveBasisSwapRates.xml (from the log above)
Pasted it into a terminal and hit enter. Problem solved😀

The rates are pretty important for the company, so this “backup procedure” is not good enough.
A you see the job attempts to fetch the rates 4 times with a 5 minute wait in between before it bombs out,
I will increase attempts from 4 to 6 and implement a backup routine that imports the daily rates if not imported and
schedule it two hours later. And create a PC emergency routine that can be run from any ‘stand alone’ Windows PC,
safeguarding the rates if the Data Warehouse servers is down, (which have not happened during it’s 17 years in operation).
Better safe than sorry.      

Here is the retrieve rates routine as it is today: (It is an ITL workflow)
