Explanation regarding the maintenance

The goal of this maintenance is to increase the stability of OSIRIS. For the past few months, OSIRIS has had problems with small faults, resulting in the system frequently being unavailable to the end users. In general, the faults do not last for long but they are inconvenient.

Analysis has shown that the OSIRIS faults are mainly on account of the problems with the UT’s storage environment, of which we are already aware. These problems then affect OSIRIS resulting in occasional non-availability of the application.

The aim of this maintenance is to move OSIRIS from the now instable storage environment, to the new stable environment especially for OSIRIS. After this move we expect a better availability, less dependency and structurally solved problems regarding the OSIRIS storage issues.

We are sorry for any inconvenience, but do anticipate that this maintenance work will improve the availability of OSIRIS.

With kind regards,

S&O and ICTS
