During this process (Saturday evening to Monday morning), there will be periods during which the CDLIS/S2S Central Site (Central Site) will be in inquiry-only mode or unavailable (over and above the regularly scheduled maintenance window of 2:00 AM ET to 5:00 AM ET on Sunday, September 29 2024). AAMVA is taking all steps possible to minimize service interruptions and will be sending alerts notifying states of Central Site availability throughout the process. Read more here.
