A denied SLA credit claim is usually not the provider refusing to pay. It is a claim that did not match the SLA text: a missing field, a downtime definition that was not met, an exclusion that does not actually apply. None of the four big providers runs a formal appeals process, because the SLAs state that the credit is your sole and exclusive remedy. That sounds final. In practice the decision was made by a support agent applying a public document, and it can be reversed with a corrected claim or an escalation, as long as the window is still open. Below: the five denial reasons, the deadline math, and the per-provider path back to a paid credit.

Providers reject SLA credit claims for a short list of reasons, and every one of them is written somewhere in the SLA. If you know which one hit you, you know whether the denial is fixable.
| Reason you were denied | The SLA language behind it | Is it fixable? |
|---|---|---|
| Missing or incomplete information | AWS: "failure to provide the requested information will disqualify you" | Yes, resubmit complete while the window is open |
| Downtime below the SLA's definition | GCP: partial minutes under one minute do not count. Azure: health advisories are not credit-eligible | Maybe, re-measure against the exact definition |
| An exclusion applies | All four: force majeure, customer-side issues, scheduled maintenance | Rarely, read the exclusion text closely |
| Claim under the wrong SLA or tier | AWS: region-level and instance-level claims cannot be stacked. GCP: single instance or multi-zone, not both | Yes, refile under the SLA that matches your setup |
| Filed too late | Every SLA sets a claim window | No, the window is the window |
Every row but the last has a second attempt attached. The SLAs disqualify incomplete claims, not the incident itself, and nothing forbids a corrected claim while the window is open. The last row ends the conversation: a late claim cannot be un-late.
AWS writes it in the Compute SLA: the service credit is your sole and exclusive remedy for any failure to provide EC2. Google's Compute Engine SLA says the same: this SLA states the customer's sole and exclusive remedy. No arbitration clause, no regulator, no small claims shortcut. The person who denied you applied a public, dated document to your claim. AWS's Compute SLA is dated May 25, 2022. Google's was last modified March 4, 2025. DigitalOcean's Droplet SLA is dated June 3, 2025. When support says no, ask which clause you missed, then read it. Most denials either fall apart or firm up in one sitting.
Your second attempt inherits the original claim window. It differs per provider:
| Provider | Claim window | Where the claim goes |
|---|---|---|
| AWS | By the end of the second billing cycle after the incident | AWS Support Center case |
| Azure | Within 2 months of the end of the billing month | Help + support, Billing, Refund Request |
| Google Cloud | Varies by service; Compute Engine gives 60 days from eligibility | Google technical support via the SLA form |
| DigitalOcean | Within 2 billing cycles of the downtime month | success@digitalocean.com |
An AWS incident on March 3 means the billing cycle ends March 31 and the claim must land by the end of May. Google's Compute Engine window starts when you become eligible, the moment the monthly uptime math crosses the SLO. If the window closed before the denial arrived, the SLA stops applying to that incident and there is nothing left to appeal.
There is no formal appeal process in any of the four SLAs. Your appeal is a corrected claim or an escalation, and it only counts while the claim window is still open. Rebuild the claim to match the SLA text and get it in before the deadline.
AWS. Open a new Support Center case or update the denied one. Reuse the exact subject line the SLA asks for: the Compute SLA wants "Amazon Compute SLA Credit Request - Region-Level Claim" or the Instance-Level variant, plus your account ID, the region, the dates and times with time zone, the resource IDs, and request logs documenting the errors. Redact anything sensitive; AWS expects asterisks. The disqualification clause applies to the incomplete claim, not to the incident, and a complete claim inside the window gets a fresh decision. If the case stalls, escalate it and ask for the specific clause behind the denial. One credit needs no claim at all: an EC2 instance unavailable for more than six minutes of a clock hour gets that hour free automatically.
Azure. Open a new support request, Billing, Refund Request, and state plainly that this is an SLA credit request. Reference the denied ticket number, attach the incident ID from Service Health (Health history), the subscription ID, and the outage window in UTC. Two details trip people up. Advisory incidents do not earn credits, and if you bought through a CSP partner, the claim goes through that partner in Partner Center, not through the portal. The window is two months from the end of the billing month, partner route included.
Google Cloud. The Compute Engine SLA says you must notify Google technical support within 60 days of becoming eligible and provide log files showing the downtime periods with their dates and times. If the claim was denied, that sentence is usually the diagnosis: the logs were missing or did not line up with Google's downtime definition, which counts only full consecutive minutes. Re-export the logs for the exact period, match them to the SLO for your tier and region, and resubmit. If you bought through a reseller, the credit applies to the reseller order, so the claim goes through them.
DigitalOcean. Email success@digitalocean.com within two billing cycles of the downtime month. Include the email address on the account, the affected Droplet resource details, and the outage dates and times. The SLA gives DigitalOcean its own determination of the uptime percentage, so a denial usually turns on their numbers, not yours. Ask for the calculation. Also check the SLA version in force on the incident date: the App Platform SLA, for example, only counts unavailability after five consecutive minutes.
Escalation has a ceiling, but it is higher than the first ticket. A senior engineer or your account team can revisit a support decision, and the SLAs reserve room for your agreement to change the terms: AWS's Compute SLA applies unless otherwise provided in your customer agreement. An enterprise agreement is a different negotiating surface than pay-as-you-go. If the denial came from a junior agent applying a checklist, ask for the clause and ask again one level up.
Some denials are correct, and spotting them saves you weeks. If the incident was scheduled maintenance, caused by your own configuration, or caused by something outside the provider's control, the exclusions apply and further claims waste time. If the credit computes under one dollar, AWS will not issue it. If your application was not sending requests during an S3 incident, the SLA's error-rate math gives you no breach to prove. Budget like an accountant: a 10% credit on a $2,000 monthly service bill is $200, which is worth two focused hours, not two weeks of ticket ping-pong.
Before you resubmit, pull the SLA for the exact service and check your claim line by line against its definitions, exclusions, and required contents. Our evidence guide walks through what each provider accepts, and the deadline tracker keeps the windows from sneaking past you. Do it today, while the incident is fresh, not after the denial lands. If matching outages to SLA text keeps failing, UptimeAudit does it for the services it monitors and hands you the drafted claim with the evidence and deadline attached. Either way, the SLA text is the referee, and it is public.
